I2Pd

The Invisible Internet Protocol (daemon) (short I2Pd or also I2P Daemon) describes itself as a full-featured C++ implementation of I2P client.

Introduction

I2Pd is a project implementing the I2P router in C++ instead of Java (in order to require less CPU power and RAM).

Performance: according to Echelon (2015-12) "On a usual system, it pushes the same data as the java version through the network. It maybe using 5-10% less CPU while doing so."

I2Pd uses significantly less memory.

Launched in 2013.

As of 2019 it almost has a full feature parity with Java I2P implementation.

Status for I2Pd and some services/software

I2Pd is a full-fledged replacement for the Java-based I2P. The following historical data reflects to some extent the history of development.

Applications that use I2CP : supported

I2Pd currently (november 2016) supports the SAM, BOB, and SOCKS interfaces. Starting from relese 2.8.0 it supports the I2CP interface, which is required for the following applications: I2PSnark, I2P-Bote, SusiMail.

Applications that use SAM, BOB, and SOCKS interfaces : supported

These interfaces are supported by I2Pd (december 2014).

Examples of applications that use them:

• libtorrent (and the clients using it, mainly qBittorrent) (SAM)
• I2P-Messenger
• iMule (SAM). Supported from I2Pd v0.9.0..
• Syndie (SOCKS ?)

Cryptography

I2Pd uses OpenSSL as major crypto library, and it's own implementation of EdDSA.

Misc

I2Pd is an I2P router and does not bring any additional software. However, all file sharing and BitTorrent clients running under I2P are supported.

I2Pd can be installed via the distributions used, if available, or obtained from the developers' homepage.
