FiSHy – Blowfish encryption for Colloquy

FiSHy is a plugin for Colloquy, providing Blowfish encryption support. You can encrypt messages you send to chat rooms or queries, and decrypt incoming messages. It also supports automatic Diffie-Hellmann key-exchanges for queries, so you can share channel-keys securely.

It fits nicely in the OS X ecosystem by saving keys in the Keychain and by using a simple Drag’n’Drop install. It is compatible with FiSH, mIRCryption and Dirt.

FiSHy uses the Blowfish and Key-Exchange engine from Dirt, an encrypting IRC proxy. So if FiSHy doesn’t work for you, or you want to use another client, please check out Dirt.

You need OS X 10.4 or higher and Colloquy 2.1 to use this. The latest version of Colloquy (2.2) contains a bug which causes FiSHy to tag encrypted messages as unencrypted. It does decrypt and display the actual message correctly, though. This bug is fixed in the Colloquy source code. So you can either compile your own, fresh Colloquy or keep using version 2.1 until Colloquy 2.3 is released.

If you don't know how to compile Colloquy you can download a version compiled by me. It is Colloquy 2.2.1 with this fix applied.
