Downloads (pre-built binaries)

Running

On Linux, make creates I2PChat executable in the current folder. Run it with ./I2PChat.

  • You will need to enable the SAM application bridge in your router: for Java I2P via Client Configuration or for i2pd via i2pd.conf's [SAM] section.
  • As of version 0.2.31, the DSA_SHA1 Signature type is no longer available. The recommended (and default) Signature Type is now: EdDSA_SHA512_Ed25519
  • Select 'Online' from the dropdown menu on the main window. When you first go online, your unique address (Destination) will be created when connecting to SAM
  • Your settings and contacts will be stored in ~/.i2pchat/ on Linux-based systems, or %APPDATA%\Roaming\I2PChat\ on Windows
