I2P Chat AKA I2P Qt Messenger

Updates now go here has new important fixes

Note: this repo is being eventually migrated to which should be considered as the main. This repo is deprecated.


How to run it

You need to enable SAM in your router on java i2p configclients page or i2pd's i2pd.conf [sam] section to make I2P Chat work over your I2P router.

Security measures

Since version 0.3.1

When building this, make sure you do not define DEBUGLOGGING. If you do define it, the app will log debug info (which includes all chat messages) to configdir/DebugLog.txt if set DebugLogging to true in General group in the app's configuration. See main.cpp and form_settingsgui.cpp for more details on DEBUGLOGGING. All versions < 0.3.1 are affected by this and are less secure.
