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. It is a Universal Binary and works on any Mac running OS X 10.4

What's New

New in 0.3.0:
  • Made FiSHy localizable.
  • Fixes a crash after a key-exchange timed out.
  • Make commands case-insensitive.
  • Make commands work in console windows, too.


  • Mac OS X 10.4 or later
  • The latest Colloquy

As i was not able to rate this plugin in my comment before, i want to make up this lapsus with this rating as i think that free-developed tools (and without any pressure to pay) in any quality should be honored with respect to the authors and their free-spended time to make the internet world a bit more fancy :-)

And as this tool is working so nice and closing the gap for intel-mac users to crypt irc chats properly it is even more a pleasure to do this in this way.
Thanks again! nose.

A very nice and useful tool for crypting messages in irc chats.
It is working excellent with Colloquy in its newest version 2.1 (3590). The very easy installation makes it worth to use it every day...
Good job and thanks for taking time to provide a easy-working solution for blowfish crypting on macs shipped with intel chips!
Thanks a lot! nose.
