I2Pソフトウェア (I2P)

The I2P Java distribution is the first I2P software gateway and has been actively developed since 2003. It includes a router, applications, and the ability to manage and customize your own connection with the I2P network using a built in Hidden Services manager

Applications are made available through a webUI that listens at The main page is called the “Router Console,” where network connection status is displayed and access to applications is provided.


The Set Up Wizard: When you download the I2P software, a set up wizard will guide you through a few configuration steps while your router is making its first connections to the network. This happens the same way that your home router connects you to the Internet. During the set up process, you will be given the option to test your bandwidth and set your bandwidth limits in order to ensure a good connection as a network peer.

The I2P Router Console: Here is where you can see your router network connections. You will be able to see how many peers you have, and other information that will help if you need to troubleshoot. You can stop and start the router as well. You will see the applications that the software includes, as well as links to some community forums and sites on the I2P network. You will receive news when there is a a new software release, and will be able to download the latest version here as well. Additionally, you can find shortcuts to other available applications. The console is customizable and includes a default light theme with a dark theme option.

SusiMail: SusiMailは、安全なEメールクライアントです。これは第一に、I2Pネットワークの内側でPostmanのEメールサーバーを使うために意図されています。他のネットワークにEメールの使用に関する情報を漏洩するのを回避するよう設計されています。SusiMailはブリッジされていて、インターネットからもEメールを送受信できます。時折、Gmailのようないくつかのサービスにスパムとして分類されるのが確認でき、あなたはインターネットEメールサービス提供者の設定内で修正できます。

I2PSnark: SnarkはI2Pネットワークのみのビットトレントクライアントです。他のネットワークを介してピアに接続することはありません。

アドレス帳: これは、人間にとって読みやすいアドレス(例: i2p-projekt.i2p)と一致するI2Pアドレス (udhdrtrcetjm5sxzskjyr5ztpeszydbh4dpl3pl4utgqqw2v4jna.b32.i2p) のローカルに定義された一覧です。 それは、他のアプリケーションとそのI2Pアドレスの場所に、人間にとって読みやすいアドレスを使えるようにし、統合します。それは、ネットワークデータベースやDNSサービスよりも、hostsファイルや連絡先一覧に似ています。これらはコンピューターを識別する世界中の名前空間に非ず、即ち、 .i2p ドメインが最終的に何に割り当てられるかは、あなたが決めることです。

The QR Code Generator: Besides the Address Book, I2P addresses can be shared by converting them into QR codes and scanning them with a camera. This is especially useful for Android devices.

I2P Hidden Services Manager This is a general-purpose adapter for forwarding services ( ie SSH ) into I2P and proxying client requests to and from I2P. It provides a variety of “Tunnel Types” which are able to do advance filtering of traffic before it reaches I2P.

I2P Network Compatible Applications

Mozilla Firefox: A web browser with advanced privacy and security features, this is the best browser to configure to browse I2P sites.

Chromium: A web browser developed by Google that is the Open-Source base of Google Chrome, this is sometimes used as an alternative to Firefox.

BiglyBT: A Feature-Rich bittorrent client including I2P support and the unique ability to “Bridge” regular torrents in-to I2P so people can download them anonymously.

OpenSSH: OpenSSH is a popular program used by systems administrators to remotely administer a server, or to provide “Shell” accounts for users on the server.

Git/Gitlab: Git is a source-code control tool which is distributed, and often recommends a fork-first workflow. Hosting source code on I2P is an important activity, so Gitlab-specific instructions are available for all to use.

Debian and Ubuntu GNU/Linux: It is possible to obtain packages for Debian and Ubuntu GNU/Linux over I2P using apt-transport-i2p and apt-transport-i2phttp. In the future, a bittorrent-based transport may also be developed.

Applications for Developers to create new things

The SAM API Bridge: The SAM API is a language-independent API for writing applications that are I2P-native by communicating with the local I2P router. It can provide Streaming-like capabilities, Anonymous Datagrams, or Repliable Datagrams.

The BOB API Bridge: This is a deprecated technology, BOB users should migrate to SAM if it is possible for them to do so.

The I2CP API: Not strictly an application, this is how Java applications communicate with the I2P router to set up tunnels, generate and manage keys, and communicate with other peers on the network.
