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 I2P router written in C++, launching in 2013 and reaching near complete feature parity with the official Java router in 2019. Being in C++ makes I2Pd less resource hungry than a JVM, making it suitable for low performance systems as a daemon (hence "I2P Daemon").

Performance (might not reflect current state): 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."^[1]

I2Pd has SOCKS Proxy enabled by default on port 4447.

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^[2].

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

These interfaces are supported by I2Pd (december 2014)^[3].

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.^[4].
Syndie (SOCKS ?)

Cryptography

I2Pd uses OpenSSL as major crypto library, and it's own implementation of EdDSA.^[5]

Misc

I2Pd is an bare-bones I2P router and does not bring any additional software alongside. However, I2P's own protocols (like SAM or I2CP), therefore programs supporting them (like file sharing and BitTorrent clients) are supported.

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