Reclaim Your Privacy!

Hyphanet makes it easy to publish and follow what others publish with strong privacy protections.

Plugins built on its decentralized data store make it very easy to host your own website and provide microblogging and forums, media sharing from files to video-on-demand and decentralized version tracking, blogging and spam resistance without central authority.

For an easy start you can join the global Opennet. For maximum privacy, connect to your friends and build a friend-to-friend network independent of and invisible to any centralized server. To access the global network, you either need some friends who also connect to opennet, or use the Shoeshop plugin to build a sneakernet that can even bridge separate friend-to-friend networks when your regional internet itself gets severed from the global information network.

Lots of additional information about Hyphanet and its history is available on Wikipedia.

Download and install Freenet:

For WindowsFor macOS, GNU/Linux & POSIX

Freenet is free and open source software available under GPLv2+. The source code is on GitHub.WindowsDownload and run the installer (

gpg signature;

keyring)Download Freenet for WindowsIt will automatically install Freenet and other required components for you.

When done, your default browser will automatically open up to Freenet's

web-based user interface.Freenet requires Windows 8.1 or later.Note: Once a Windows version reaches end of life, we do not guarantee

any longer support, or the fact that Freenet will install and/or work in

such environments. However, it is not mandatory that Freenet will not work

on an older Windows OS. We always strongly recommend you to take security

very seriously, and run up to date software that receives security updates,

to be on the safe side.

GNU/Linux & POSIX

Get the Java-based installer (

gpg signature;

keyring).Download Freenet for GNU/Linux & POSIX

Run the file with Java, then follow the installer:You need to have a recent Java Runtime Environment (JRE), for

example

OpenJDK which can be obtained via your

package manager or from

https://adoptopenjdk.net.Java version 9 or higher is required.If there are problems, use the command line. This requires

wget which can be installed with a package manager, such as

sudo apt-get install wget on Debian or Ubuntu.wget 'https://www.draketo.de/dateien/freenet/build01496/new_installer_offline_1496.jar' -O new_installer_offline.jar;

java -jar new_installer_offline.jar;

To install on a headless system, or if you get fontconfig problems, use the -console option and follow the prompts:java -jar new_installer_offline.jar -console;

Note: We would love to have packages for most distributions.

There is a

package for Gentoo, and

a preliminary but un-maintained

Debian package.

If you would like to help, it would be much appreciated!Note: On some systems (including FreeBSD and OpenBSD) the wrapper does

not work, unless you install additional software packages and configure it.

You can start Freenet manually there, but you then don’t have

auto-updates. After installation you find the relevant classpath

arguments in wrapper.conf. Then call java directly with a command like

java -Xmx1500m -Xss512k -Dnetworkaddress.cache.ttl=0 -Dnetworkaddress.cache.negative.ttl=0 --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED -cp bcprov-jdk15on-1.59.jar:freenet-ext.jar:freenet.jar:jna-4.5.2.jar:jna-platform-4.5.2.jar:pebble-3.1.5.jar:unbescape-1.1.6.RELEASE.jar:slf4j-api-1.7.25.jar freenet.node.NodeStarterRelease MirrorOur releases are provided via Lysator. You can try the

http mirror or the

tor mirror

provided by

Lysator.Alternatively you can use the github release.Mirrored installationIf you have a working Freenet installation directory that you have mirrored

from one Unix machine to another (e.g. via rsync or unison), enabling the

mirrored installation is not difficult. Nothing in a Freenet installation

cares about its host's IP address; it can't, or Freenet would fail on

machines that get IP addresses from a DHCP pool.All you actually need to do is tell the system you've mirrored to that it

should start the Freenet proxy daemon for you on boot. Do crontab -l

on the source machine, find the line that is tagged "FREENET AUTOSTART" and

add that to your crontab on the mirrored machine.However: each installation has a unique identity key generated at

installation time. If you try to run two instances with the same identity at

the same time, both proxy demons will become confused and upset. Don't do

this!Using FreenetPlease try the step by step guide to setting up Freenet and various Freenet apps,

especially if installing on macOS.

We are not responsible for unofficial third party apps it recommends (including FMS),

but many Freenet users and developers use them.Firewalls and routersFreenet should work fine with most routers, but if you are having problems

and you have a firewall or router, click here for

some info.So it's running, what do I do?When the installer closes, it should open a browser window pointing to the

first-time wizard. Here you can configure basic settings, and then start

using Freenet. You can access Freenet later on via the system tray menu (

bottom right on the screen), or use the Browse Freenet shortcut on the

desktop and/or start menu. If it doesn't work, open

http://127.0.0.1:8888/ in your web browser.For best security you should use a separate browser for Freenet, preferably

in privacy mode. On Windows, the system tray menu will try to use Chrome in

incognito mode if possible. Internet Explorer does not work well with

Freenet, Firefox and Opera are widely used.If you know anyone running Freenet, you can improve your security and help to

build a robust network by connecting to their node. First, open the Add a

friend page. You and your friend should

each download their "node reference". Send the file to the other person,

and add his node reference using the form at the bottom of the page. When

both are added, your friend's node should show up on the Friends page,

probably as "CONNECTED" or "BUSY". You can set a name for your node on the

config page to make it easier to see who it is. Only add nodes run by people

you actually know, whether online or offline, as adding total strangers

harms performance and does not improve security much (they could be the bad

guys!).So I'm connected, what do I do?Freenet itself includes anonymous websites ("freesites"), filesharing,

searching, and more, but you can also use third party applications for chat,

filesharing, to help you upload freesites, etc.The Freenet Social Networking Guide explains

how to set up the main third party tools, including email, forums and

micro-blogging (Sone, a bit like twitter).It doesn't work, now what?If you have problems installing or running Freenet, please see the knowledge base,

FAQ,

chat, or

mailing list.Hardware requirementsGenerally a 1GHz processor and 1GB of RAM should be fine. Freenet will run on

smaller systems, but it uses at least 128MB of RAM, so unless the system does

nothing else it will struggle in less than 512MB. However, the processor is

less of a problem, people have been known to run it on 400MHz Pentium 2's or

ATOM's, although downloads and browsing would be slow.Freenet will use a portion of your disk for storing data, you can configure

this to any size from 100MB upwards, but we recommend at least 1GB. Freenet

also uses disk space for your downloads. Freenet's memory usage is

approximately 256MB plus 400kB for every 2GB of datastore.On 64-bit Windows, we will install a 32-bit Java Virtual Machine because of

limitations of the Java Service Wrapper.UpgradingFreenet provides an upgrade-over-Freenet mechanism: It will keep itself up to

date automatically from other Freenet nodes, and this will normally work even

if it is unable to route to them due to them being too new. This is anonymous

and secure, and we recommend people use it. However, if something is severely

broken, you can upgrade your node manually from our servers:

Windows users can upgrade to the latest-stable Freenet release

by running update.cmd in the Freenet directory.macOS, GNU/Linux, or other POSIX users may upgrade by running the update.sh

shell script in the Freenet directory.

Add friends (or connect to strangers)If you know other people who also use Freenet, you can add them as Friends.

This will make you safer against attacks on Freenet Project infrastructure

(the

seednodes).Once you are connected to 5 or more friends, you can enable high security mode.

In high security mode Freenet will only connect to your friends.

This makes your usage of Freenet almost undetectable,

but you are still able to access the rest of the network through your friends' friends friends ....You don't have to add friends right now.

If you use a "low" or "normal" security level Freenet will automatically connect to strangers and will work just fine.

However, your (or someone else's) government may be able to find out who you are with enough effort. Be careful!Verifying SignaturesDownload the Freenet Project signing keys and import them into your keyring: pub 2048R/0xEAC5EBF07AA9C2A3 2013-04-29

什么是 Freenet？

I worry about my child and the Internet all the time, even though she's too

young to have logged on yet. Here's what I worry about. I worry that 10 or

15 years from now, she will come to me and say 'Daddy, where were you when

they took freedom of the press away from the Internet?

--Mike Godwin, Electronic Frontier Foundation

Freenet 是一个免费软件，您可以通过它匿名的分享文件、浏览和发布“Freesite”（只能在 Freenet 网络中访问的网站）、在论坛中发帖，不用担心被审查。Freenet 是去中心化的，很难被攻击。如果使用它的“暗网（Darknet）”模式，用户仅会连接到他们的好友，那么他人很难侦测到这个用户。Freenet 节点之间的通讯是加密的，并通过其他节点路由。因此要了解谁在请求某些信息、请求的内容是什么，是极其困难的。用户通过贡献自己的互联网带宽和他们的一部分硬盘空间（称为“数据存储（Data Store）”）来储存文件。根据文件的流行程度，文件会自动被保留或删除。不流行的文件被删除，可以腾出更多的空间给流行的文件。文件是加密的，因此用户无法轻易得知它的“数据存储”内储存了什么内容，因此也不会因其被追究责任。聊天论坛、网站和搜索功能，都是基于该分布式“数据存储”构建。Freenet 自诞生起已被下载超过 200 万次，用来在全世界分发敏感受审查的信息，包括中国和中东国家。Freenet 中的先驱思想和概念也深深影响了学术界。我们在 2000 年的论文《Freenet：一个分布式匿名信息存储和接收系统》（Freenet: A Distributed Anonymous Information Storage and Retrieval System）， 是 2000 年被引用次数最多的计算机科学论文（来源：Citeseer）。Freenet 也给世界法律和哲学论文带来了灵感。Ian Clarke，Freenet 的创造者和项目协调人，被 2003 年《麻省理工科技评论 》杂志（MIT's Technology Review）评为世界百强革新者。在最近的开发中，我们引入了一个重要的功能（在其他类似网络中鲜见），称为“暗网（Darknet）”：用户仅与自己信任的人互相连接，这能够极大的降低他们的风险，同时仍然能够通过他们朋友的朋友的朋友来连接到整个 Freenet 网络。这能够让那些“使用 Freenet 即违法”的地方的人们使用 Freenet。政府很难封禁它，用户无需“翻墙隧道”就可以进入“自由的世界”。Written by Ian Clarke

The Philosophy Behind Freenet

A Disclaimer

There are many reasons why people get involved in the Freenet Project. Some

share the views outlined in this document; some share variations of these views,

which are also served by what we are trying to achieve; and some just enjoy the

technical challenge. These are the ideas which motivated me to architect the

system in the first place, but not necessarily the views that everyone involved

in the Freenet Project holds.

Suggested prior reading

For this document to make sense, you should probably know what Freenet is. You

can get a good overview from What is Freenet?.

The importance of the Free flow of information

Freedom of speech, in most western cultures, is generally considered to be one

of the most important rights any individual might have. Why is the freedom to

share ideas and opinions so important? There are several ways to answer this

question.

Communication is what makes us human

One of the most obvious differences between mankind and the rest of the animal

kingdom is our ability to communicate sophisticated and abstract concepts. While

we constantly discover that animal's communication ability is more sophisticated

than previously assumed, it is unlikely that any other animal approaches our own

level of ability in this area.

Knowledge is good

Most people, given the option of knowing something and not knowing something,

will choose to have more information rather than less. Wars have been won and

lost over who was better-informed. This is because being better-informed allows

us to make better decisions, and generally improve our ability to survive and be

successful.

Democracy assumes a well informed population

Many people today live under democratic governments, and those who don't,

probably want to. Democracy is an answer to the question of how to create

leaders, while preventing them from abusing that power. It achieves this by

giving the population the power to regulate their government through voting,

yet the ability to vote does not necessarily mean that you live in a

democratic country. For a population to regulate their government effectively

it must know what their government is doing, they must be well informed. It

is a feedback loop, but this loop can be broken if the government has the

power to control the information the population has access to.

Censorship and freedom

Everyone values their freedom, in fact, many consider it so important that

they will die for it. People like to think that they are free to form and

hold whatever opinions they like, particularly in western countries. Consider

now that someone had the ability to control the information you have access

to. This would give them the ability to manipulate your opinions by hiding

some facts from you, by presenting you with lies and censoring anything that

contradicted those lies. This is not some Orwellian fiction, it is standard

practice for most western governments to lie to their populations, so much

so, that people now take it for granted, despite the fact that this

undermines the very democratic principles which justify the government's

existence in the first place.

The solution

The only way to ensure that a democracy will remain effective is to ensure

that the government cannot control its population's ability to share

information, to communicate. So long as everything we see and hear is

filtered, we are not truly free. Freenet's aim is to allow two or more people

who wish to share information, to do so.

Isn't censorship sometimes necessary?

Of course no issue is black and white, and there are many who feel that

censorship is a good thing in some circumstances. For example, in some

European countries propagating information deemed to be racist is illegal.

Governments seek to prevent people from advocating ideas which are deemed

damaging to society. There are two answers to this however. The first is that

you can't allow those in power to impose "good" censorship, without also

enabling them to impose "bad" censorship. To impose any form of censorship a

government must have the ability to monitor and thus restrict communication.

There are already criticisms that the anti-racism censorship in many European

countries is hampering legitimate historical analysis of events such as the

second world war.

The second argument is that this "good" censorship is counter-productive even

when it does not leak into other areas. For example, it is generally more

effective when trying to persuade someone of something to present them with

the arguments against it, and then answer those arguments. Unfortunately,

preventing people from being aware of the often sophisticated arguments used

by racists, makes them vulnerable to those arguments when they do eventually

encounter them.

Of course the first argument is the stronger one, and would still hold-true

even if you didn't accept the second. Basically, you either have censorship,

or you don't. There is no middle-ground.

But why is anonymity necessary?

You cannot have freedom of speech without the option to remain anonymous.

Most censorship is retrospective, it is generally much easier to curtail free

speech by punishing those who exercise it afterward, rather than preventing

them from doing it in the first place. The only way to prevent this is to

remain anonymous. It is a common misconception that you cannot trust

anonymous information. This is not necessarily true, using digital signatures

people can create a secure anonymous pseudonym which, in time, people can

learn to trust. Freenet incorporates a mechanism called "subspaces" to

facilitate this.

And what of copyright?

Of course much of Freenet's publicity has centered around the issue of

copyright, and thus I will speak to it briefly. The core problem with

copyright is that enforcement of it requires monitoring of communications,

and you cannot be guaranteed free speech if someone is monitoring everything

you say. This is important, most people fail to see or address this point

when debating the issue of copyright, so let me make it clear:

You cannot guarantee freedom of speech and enforce copyright law

It is for this reason that Freenet, a system designed to protect Freedom of

Speech, must prevent enforcement of copyright.

But how will artists be rewarded for their work without copyright?

Firstly, even if copyright were the only way that artists could be rewarded

for their work, then I would contend that freedom is more important than

having professional artists (those who claim that we would have no art do not

understand creativity: people will always create, it is a compulsion,

the only question is whether they can do it for a living).

Secondly, it could be questioned whether copyright is effective even now. The

music industry is one of the most vocally opposed to enhancements in

communication technology, yet according to many of the artists who should be

rewarded by copyright, it is failing to do so. Rather it has allowed

middle-men to gain control over the mechanisms of distribution, to the

detriment of both artists and the public.

Alternatives to Copyright

Fortunately it won't come to this. There are many alternative ways to reward

artists. The simplest is voluntary payment. This is an extension of the

patronage system which was frequently used to reward artists prior to

copyright, where a wealthy person would fund an artist to allow them to

create full-time. The Internet permits an interesting extension of this idea,

where rather than having just one wealthy patron, you could have hundreds of

thousands, contributing small amounts of money over the Internet.

We actually practice what we preach in this regard too, on the 15th of March

2001 the Freenet Project started taking donations, and within a week we had

collected over $1000.

Freenet 0.7.5 build 1497 is now available. [overview]

This release fixes a severe vulnerability in path folding that allowed

to distinguish between downloaders and forwarders with an adapted

node that is directly connected via opennet.

This vulnerability was reported to the Project by Prof. Ming Yang and

Prof. Zhen Ling from the School of Computer Science and Engineering,

Southeast University, Prof. Xinwen Fu from the Miner School of

Computer & Information Sciences, University of Massachusetts Lowell,

and Yonghuan Xu from School of Cyber Science and Engineering,

Southeast university.

Yonghuan also provided support in fixing the vulnerability. Thank you

very much!

To reduce the probability of hitting other problems in path folding,

we also merged the pull-request to completely avoid path folding at

HTL 17 or higher.

Thank you for using Freenet!

To reduce the probability of hitting other problems in path folding,

we also merged the pull-request to completely avoid path folding at

HTL 17 or higher.

Due to changes in the infrastructure, this release has to re-use the

Windows Installer from 1496, so newly installed nodes on Windows will

still be vulnerable for a few minutes after installation until they

auto-update. This should get fixed in 1498.

Besides this change, there’s a German translation fix by an anonymous

contributor: Email → E-Mail.

And a fix for a test that points towards the need to check the

compression code on newer JDKs.

Freenet 0.7.5 build 1496 is now available.

Fix keepalive

-------------

This fixes breakage in keepalive by ignoring a negative maxsize.

This was broken by a fix to the client

to actually honor the maxsize which was ignored before,

so ignoring invalid values provides a compatibility layer

for old plugins.

Update translations

-------------------

Imported updated translations from transifex.

The biggest changes were done by the Russian team,

adding or updating almost 200 translations.

The German team changed over 70 translations.

And 1 to 7 changes were done by teams

es, fa, fi, fr, hu, it, ja, nb-no,

nl, pt (br and PT), sv, zh-cn and zh-tw.

A big thank you for your work!

Bookmark curation

-----------------

Replaced the unmaintained freemail site in the default bookmarks

by a maintained one — thanks to Cynthia!

---------------

- add meta charset tests

- add missing test annotations — thanks to vwoodzell!

Freenet 0.7.5 build 1495

2022-12-29

Freenet 0.7.5 build 1495 is now available with many improvements.

New users

There is a new firsttime wizard for single-step setup, contributed

by redwerk and finally merged after resolving dependency-requirements.

To further ease the start, the bookmarks are re-organized with

"starting points" at the top.

User experience

For integration in browser extensions, TheSeeker added support for

the schemes web+freenet and ext+freenet which do not need further

allow-listing by browsers to use.

CometZ@6DtYG~ created a new theme sky-dark-static, a clean dark scheme,

simpler than Winterfacey.

To enable more beautiful Freesites, Spider Admin, naejadu and vwoodzell

extended the CSS filter to enable sticky, transition, and word-wrap.

The m3u-player is now only inserted into sites which contain at least

one video or audio tag. When a part of a stream fails, it is now skipped,

allowing for continuous playback without user-intervention.

Performance

For better lifetime of larger files, the healing size is increased

from 16 to 256 MiB, so a 512 MiB file will keep working if accessed

once every 10 days. To keep alive files explicitly, you can use the

keepalive plugin.

And the pending keys optimizations by Eleriseth should reduce the CPU

load on very fast nodes with many peers.

Further technical improvements

finally merged the HashingAPI by unixninja92, a GSoC project that had

gotten lost in the pull requests. This provides an easy and

well-tested way to create and verify different types of Hashes from byte

arrays, including Sha256 and TigerTree.

#258

old announcement fixes by toad were finally merged

unit tests were upgraded to junit4, thanks to vwoodzell!

the client getter method now honors the max size argument

Thank you for using Freenet!

build01494: 2022-06-25

Freenet 0.7.5 build 1494 is now available.

This build improves four broad areas:

streaming on demand,

configuration,

security, and

bugfixes.

Streaming provides improved video and audio:

Video sizes are more robust when the size changes between subsequent videos.

Audio tags no longer try to display the overlay.

This finally enables convenient Samizdat Radio

To help modernize the configuration of existing nodes,

Freenet now shows a user alert once every Freenet update if the datastore is

below 10% of available space with a link to the store size wizard page

to make it easy to increase the store. Thanks to Trivuele!

Also the bandwidth settings now parse the bit suffix correctly

(lowercase b in kbps is bit, not byte).

The security received improvements both for friend to friend mode,

for opennet, and to tools for Freesites:

Friend-to-Friend mode now randomizes pitch black defense times

and waits at least 12 hours between pitch black mitigations

to prevent timing attacks.

Opennet is hardened by disabling the write local to datastore

functionality when opennet is enabled; it can be useful on a

small darknet, but on opennet it makes it easier to find downloaders.

Thanks to Trivuele!

Also a FOAF mitigation was fixeb that wasn't operational, because it lacked

a conversion to percent. Thanks to freedom-of-depression!

The /imagecreator/ tool, among other changes, now ensures

that requested image sizes are sane — thanks to Oleh from Redwerk

Finally it’s now easier to build fred without network access. Thanks to Trivuele!

In addition to these improvements, bugs got fixed:

fix build with modern Java: add opens jvmargs on java 17.

remove Frost on ChatForumsToadlet from non-updated translations

(removed 2019 from the original english).

fix parts of the German translation.

Do not store blocks in the cache, if they are eligible for the store

(should increase usable cache size). Thanks to Trivuele!

A big thank you to all contributors and reviewers

for getting this release in shape!

And thank you for using Freenet!

build01493: 2022-03-28

Freenet 0.7.5 build 1493 is now available. [overview]

This build provides four core improvements:

Curated default bookmarks, including an actively maintained index and Shoeshop for sneakernet

Better peer scaling for very fast nodes

Updated defaults to adapt to the higher capacities of modern systems.

Compatibility with Java 17, first in the installers, with the following update for all nodes

The curated default bookmarks provide a much better first-start

experience. Previously new users saw mostly outdated sites in

inactive indexes.

Adding Shoeshop to enable sneakernet which can connect separate

Freenet networks even if no internet connection can be established

now provides all the tools for selfpublishing, not only in the

style of publishing an online blog (which is already easy with

Sharesite) or sending a file to an independent printer, but in the

much more self-reliant style, resourcefulness and rebellious spirit

of classical samizdat.

Adjusted peer-scaling fixes a conceptual problem: Fast nodes could

not utilize their bandwidth well enough, because the previous

peer-scaling did not take the aggregated bandwidth limit of the

peers into account. Now very fast nodes have linearly scaling

peer-counts to make it more likely that the capacity of their peers

added together matches the capacity of the fast node. The absolute

upper limits stay in place, because they are needed to preserve

privacy. There are also no changes to the peer-scaling of slower

nodes.

The fixed scaling should improve the performance of the whole

network because it avoids creating artificial bottlenecks.

Changes to the defaults are a doubled thread limit of newly

installed nodes (increased from 500 to 1000), with the stack size

per thread reduced by half to avoid higher memory consumption, the

datastore size is increased from 20GiB to 100GiB, because SSDs are

much faster and more resilient than before, and the default

bandwidth to offer if the actual speed cannot be found is doubled

to 32KiB/s.

These newer defaults should also improve the first-time user

experience.

Compatibility with Java 17 took longer than we hoped, because it

required deploying a newer wrapper and changes to the classpath.

This makes it easier to support packages for modern Linux, and it

should avoid losing nodes when Java updates itself (starting from

the next update this also applies to existing nodes; we have to

deploy the update code in 1493 so it can run during the update to

1494).

All together these changes should improve the user experience for

new people, give sneakernet the visibility it deserves, and

increase the performance of the network as a whole.

And last, but definitely not least, our translation team at

transifex updated enough of the the German, Persian, Finnish,

Italian, Japanese, Norwegian, Portuguese, Russian, and Swedish

texts in Freenet that we can ship the new versions. Thank you

very much!

That Freenet can keep moving forward and help people worldwide to

exercise their basic rights and freedoms is the work of amazing

volunteers, both contributors and people running Freenet nodes.

Thank you for your contributions, and thank you for using Freenet!

Very fast nodes have more peers to fix a conceptual mistake

(did not take the aggregated bandwidth limit of the peers into account).

Thanks to TheSeeker for the review!

more resilient noderef parsing for easier friend-to-friend connections

try replacing spaces by newlines in noderefs when parsing fails

Accept FreenetURI in add peer field; only try regular url on failure

Updater changes to add Java 17 support for existing nodes to

wrapper.conf (required module opens for Java 17 to wrapper.conf)

during the following update (to 1494)

add output of filtered file to the OggFilterTest

Installer changes:

Java 17 support

increase default datastore size to 100GiB, because SSDs are much

faster today

Set standard thread limit to 1000

decrease default thread stack size for reduced memory usage

Freenet build 1492: video, diagnostics, pitch black mitigation, and plugin updates

Freenet 0.7.5 build 1492 is now available. [overview]

This release finalizes the mitigation of the pitch black attack

with a test that shows that the mitigation is effective at

reducing the impact of the attack and recovering from it.

This mitigation was sponsored by nlnet as part of the

Horizon 2020 program of the EU: https://nlnet.nl/project/Freenet-Routing/

The video-player was optimized to prevent most visual flickering.

To help performance analysis, there is now a diagnostics component

with thread runtime information. You can activate it in the advanced core settings of your node.

Thanks to DC*.

And several plugins received updates:

KeyUtils got bugfixes from TheSeeker

Library now searches all indexes if you just hit search — thanks to redwerk.

Library now also allows setting a custom link suffic (docname) — thanks to TheSeeker.

Spider got bugfixes from redwerk and juiceman.

FlogHelper provides simple clickable audio and video tags.

Just put a m3u link into the video tag to have video-on-demand.

Included Bugfixes if fred (the Freenet Reference Daemon):

skip in support.io.SkipShieldingInputStream must return

non-negative. Thanks to dennisnez.

NodeConfig was reading a particular config from default on every

start up. Thanks to desyncr.

OpenJDK 16+ compat: add wrapper.conf argument to allow access to

internal openjdk modules.

Correct "current size" option in Wizard => datastore size.

Thanks to AC4BB21B.

Sidenote: What is the pitch black attack?

On Freenet, every node has a location on a circle.

To optimize routing, pure friend-to-friend nodes (no opennet)

swap these locations (without changing connections).

The pitch black attack steals the locations one by one

and replaces them with a single one,

so that after a while all nodes are at the same location.

Then no sensible routing is possible anymore.

The mitigation detects when parts of the circle are devoid of routing nodes

and fills up the holes by switching there.

If you want to help us get better, please help us get the current

pending pull-requests in shape for merging, by reviewing and/or by

improving already reviewed but inactive pull-requests

(only on clearnet, because the pull-requests are there):

https://github.com/freenet/wiki/wiki/Large-Pull-requests-that-need-work

We now also have a list of high-impact tasks:

USK@xPkwhS3czAr5oi6yNgLQ7Ld7RbUZuY6eGniS0n5FZtc,WXVIZrZyLlZugJgJKYvbF9SPfKAUAQX9gAX6g7FGNVE,AQACAAE/high-impact-tasks/0

That said: If someone asks you "what is Freenet", you could for example answer:

Freenet is a peer-to-peer platform for

censorship-resistant and privacy-respecting

publishing and communication.

or

Freenet is a communication system that covers the needs for protection

expected from a secure data broker for Multi-Party Data Exchange in IoT for Health.

(source: https://www.igi-global.com/chapter/using-freenet-as-a-broker-for-multi-party-data-exchange-in-iot-for-health/257911 )

This is what Freenet already accomplished.

And we could only get this far together, because without users,

it is hard for sofware to make a difference.

Thank you for using Freenet!

Download

Download and install Hyphanet:

For Windows

For macOS, GNU/Linux & POSIX

Hyphanet is free and open source software available under GPLv2+. The source code is on GitHub.

Windows

Download and run the installer (gpg signature; keyring)

Download Hyphanet for Windows

It will automatically install Hyphanet and other required components for you.

When done, your default browser will automatically open up to Hyphanet's

web-based user interface.

Hyphanet requires Windows 8.1 or later.

Free code signing provided by

SignPath.io, certificate by SignPath

Foundation.

Note: Once a Windows version reaches end of life, we do not guarantee

any longer support, or the fact that Hyphanet will install and/or work in

such environments. However, it is not mandatory that Hyphanet will not work

on an older Windows OS. We always strongly recommend you to take security

very seriously, and run up to date software that receives security updates,

to be on the safe side.

GNU/Linux & POSIX

Get the Java-based installer (gpg signature; keyring).

Download Hyphanet for GNU/Linux & POSIX

Run the file with Java, then follow the installer:

You need to have a recent Java Runtime Environment (JRE), for

example OpenJDK which can be obtained via your

package manager or from

https://adoptopenjdk.net.

Java version 9 or higher is required.

If there are problems, use the command line. This requires

wget which can be installed with a package manager, such as

sudo apt-get install wget on Debian or Ubuntu.

wget 'https://www.draketo.de/dateien/freenet/build01497/new_installer_offline_1497.jar' -O new_installer_offline.jar;

java -jar new_installer_offline.jar;

To install on a headless system, or if you get fontconfig problems, use the -console option and follow the prompts:

java -jar new_installer_offline.jar -console;

Note: We would love to have packages for most distributions. There

is a package for Gentoo, and a

Debian package. The debian

Package also works on WSL2 (but not WSL1). If you would like to help,

it would be much appreciated!

Note: On some systems (including FreeBSD and OpenBSD) the wrapper does

not work, unless you install additional software packages and configure it.

You can start Hyphanet manually there, but you then don’t have

auto-updates. After installation you find the relevant classpath

arguments in wrapper.conf. Then call java directly with a command like java -Xmx1500m -Xss512k -Dnetworkaddress.cache.ttl=0 -Dnetworkaddress.cache.negative.ttl=0 --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED -cp bcprov-jdk15on-1.59.jar:freenet-ext.jar:freenet.jar:jna-4.5.2.jar:jna-platform-4.5.2.jar:pebble-3.1.5.jar:unbescape-1.1.6.RELEASE.jar:slf4j-api-1.7.25.jar freenet.node.NodeStarter

Release Mirror

Our releases are provided via Lysator. You can try the

http mirror or the tor mirror

provided by Lysator.

Alternatively you can use the github release.

Mirrored installation

If you have a working Hyphanet installation directory that you have mirrored

from one Unix machine to another (e.g. via rsync or unison), enabling the

mirrored installation is not difficult. Nothing in a Hyphanet installation

cares about its host's IP address; it can't, or Hyphanet would fail on

machines that get IP addresses from a DHCP pool.

All you actually need to do is tell the system you've mirrored to that it

should start the Hyphanet proxy daemon for you on boot. Do crontab -l

on the source machine, find the line that is tagged "FREENET AUTOSTART" and

add that to your crontab on the mirrored machine.

However: each installation has a unique identity key generated at

installation time. If you try to run two instances with the same identity at

the same time, both proxy demons will become confused and upset. Don't do

this!

Using Hyphanet

Please try the step by step guide to setting up Hyphanet and various Hyphanet apps,

especially if installing on macOS.

We are not responsible for unofficial third party apps it recommends (including FMS),

but many Hyphanet users and developers use them.

Firewalls and routers

Hyphanet should work fine with most routers, but if you are having problems

and you have a firewall or router, click here for

some info.

So it's running, what do I do?

When the installer closes, it should open a browser window pointing to the

first-time wizard. Here you can configure basic settings, and then start

using Hyphanet. You can access Hyphanet later on via the system tray menu (

bottom right on the screen), or use the Browse Hyphanet shortcut on the

desktop and/or start menu. If it doesn't work, open

http://127.0.0.1:8888/ in your web browser.

For best security you should use a separate browser for Hyphanet, preferably

in privacy mode. On Windows, the system tray menu will try to use Chrome in

incognito mode if possible. Internet Explorer does not work well with

Hyphanet, Firefox and Opera are widely used.

If you know anyone running Hyphanet, you can improve your security and help to

build a robust network by connecting to their node. First, open the Add a

friend page. You and your friend should

each download their "node reference". Send the file to the other person,

and add his node reference using the form at the bottom of the page. When

both are added, your friend's node should show up on the Friends page,

probably as "CONNECTED" or "BUSY". You can set a name for your node on the

config page to make it easier to see who it is. Only add nodes run by people

you actually know, whether online or offline, as adding total strangers

harms performance and does not improve security much (they could be the bad

guys!).

So I'm connected, what do I do?

Hyphanet itself includes anonymous websites ("freesites"), filesharing,

searching, and more, but you can also use third party applications for chat,

filesharing, to help you upload freesites, etc.

The Hyphanet Social Networking Guide explains

how to set up the main third party tools, including email, forums and

micro-blogging (Sone, a bit like twitter).

It doesn't work, now what?

If you have problems installing or running Hyphanet, please see the knowledge base, FAQ, chat, or mailing list.

Hardware requirements

Generally a 1GHz processor and 1GB of RAM should be fine. Hyphanet will run on

smaller systems, but it uses at least 128MB of RAM, so unless the system does

nothing else it will struggle in less than 512MB. However, the processor is

less of a problem, people have been known to run it on 400MHz Pentium 2's or

ATOM's, although downloads and browsing would be slow.

Hyphanet will use a portion of your disk for storing data, you can configure

this to any size from 100MB upwards, but we recommend at least 1GB. Hyphanet

also uses disk space for your downloads. Hyphanet's memory usage is

approximately 256MB plus 400kB for every 2GB of datastore.

On 64-bit Windows, we will install a 32-bit Java Virtual Machine because of

limitations of the Java Service Wrapper.

Upgrading

Hyphanet provides an upgrade-over-Hyphanet mechanism: It will keep itself up to

date automatically from other Hyphanet nodes, and this will normally work even

if it is unable to route to them due to them being too new. This is anonymous

and secure, and we recommend people use it. However, if something is severely

broken, you can upgrade your node manually from our servers:

Windows users can upgrade to the latest-stable Hyphanet release

by running update.cmd in the Hyphanet directory.

macOS, GNU/Linux, or other POSIX users may upgrade by running the update.sh

shell script in the Hyphanet directory.

Add friends (or connect to strangers)

If you know other people who also use Hyphanet, you can add them as Friends.

This will make you safer against attacks on Hyphanet Project infrastructure

(the seednodes).

Once you are connected to 5 or more friends, you can enable high security mode.

In high security mode Hyphanet will only connect to your friends.

This makes your usage of Hyphanet almost undetectable,

but you are still able to access the rest of the network through your friends' friends friends ....

You don't have to add friends right now.

If you use a "low" or "normal" security level Hyphanet will automatically connect to strangers and will work just fine.

However, your (or someone else's) government may be able to find out who you are with enough effort. Be careful!

Why we do this

I worry about my child and the Internet all the time, even though she's too young to have logged on yet. Here's what I worry about. I worry that 10 or 15 years from now, she will come to me and say Daddy, where were you when they took freedom of the press away from the Internet

Freenet Manual

Introduction

Freenet is a distributed, decentralized alternative to the centralized World

Wide Web, designed to unleash a new era of innovation and competition, while

protecting freedom of speech and privacy.

At the core of Freenet is the Freenet kernel, which runs on users' computers,

smartphones, or other devices. The kernel is tiny, less than 5 MB, allowing it

to be installed in a matter of seconds and is compatible with a wide range of

hardware.

Freenet is a peer-to-peer network, which means

that computers that are part of the network self-organize into a global network

without any central authority, and the work of hosting services is distributed

among the users.

Freenet

This page is built with Kweb, which

requires JavaScript to be enabled. Freenet Dev FAQ BlogDeclare your digital independenceThe centralization of the internet poses a fundamental threat to individual freedom. In 2024, a few corporations control most internet services and infrastructure. These corporations wield immense power over most of us with little accountability, enabling them to censor content, exploit our data, and exclude users from services they depend on —all with profound implications for democracy. We need a solution urgently.

Introducing Freenet — a decentralized replacement for the world wide web. Acting as a global, shared, decentralized computing platform, Freenet can either be accessed via a standard web browser or integrated into third-party applications.

Freenet is not merely a tool for developers; it offers a pathway for anyone seeking greater control and freedom in their digital interactions. You can build or use decentralized services for messaging, social media, email, and e-commerce. These applications are designed for scalability and interoperability, secured through modern cryptographic techniques.

Freenet

The Internet has grown increasingly centralized over the past two decades, such

that a handful of companies now effectively control the Internet infrastructure.

The public square is privately owned, threatening freedom of speech and

democracy.

Freenet is a software platform that makes it easy to create decentralized

alternatives to today's centralized tech companies. These decentralized apps

will be easy to use, scalable, and secured through cryptography.

To learn more about Freenet as a developer read The User

Manual. For an introduction to Freenet watch Ian's

talk and Q&A - YouTube /

Vimeo.

Status

Freenet is currently under development. Using our development

guide, developers can experiment with

building decentralized applications using our SDK and testing them locally.

Applications

Examples of what can be built on Freenet include:

Decentralized email (with a gateway to legacy email via the @freenet.org

domain)

Decentralized microblogging (think Twitter or Facebook)

Instant Messaging (Whatsapp, Signal)

Online Store (Amazon)

Discussion (Reddit, HN)

Video discovery (Youtube, TikTok)

Search (Google, Bing)

All will be completely decentralized, scalable, and cryptographically secure. We

want Freenet to be useful out-of-the-box, so we plan to provide reference

implementations for some or all of these.

How does it work?

Freenet is a decentralized key-value database. It uses the same small

world routing algorithm as

the original Freenet design, but each key is a cryptographic contract

implemented in Web Assembly, and the value

associated with each contract is called its state. The role of the

cryptographic contract is to specify what state is allowed for this contract,

and how the state is modified.

A very simple contract might require that the state is a list of messages, each

signed with a specific cryptographic keypair. The state can be updated to add

new messages if appropriately signed. Something like this could serve as the

basis for a blog or Twitter feed.

Freenet is implemented in Rust and will be available across all major operating

systems, desktop and mobile.

What is Locutus?

Locutus was the working title used for this successor to the original Freenet,

in March 2023 it was renamed to "Freenet", this repository was

renamed from locutus to freenet-core in September 2023.

What is Hyphanet?

The original Freenet codebase is now called Hyphanet. It is still actively

developed by the same maintainers as before, and is available

here.

Many developers are active in r/freenet,

but remember that Reddit engages in political and ideological censorship so

don't make this your only point of contact with us.
