This is a recompile of to make it work on 64 bit windows and to work with AdiIRC, source code is attached.

Since this is made to inject itself into the mIRC's underlying sockets and AdiIRC is a completely different program, all events must be scripted to use the fish functions from the dll, some events is already added in the attached script, feel free to add more as needed.

A proper plugin will probably be added at some point using the AdiIRC API V2 instead of a script.

Thanks to ParAd0x for creating this project.

Compiled with OpenSSL-1_0_2o binaries from

How to install

Use blowfish64 on 64 bits version of AdiIRC, otherwise 32 bits (type //echo -ag $bits to verify).

Step 1. Download the attached (Cliok on the Files link at the bottom)
Step 2. Unpack into $adiircdir\Scripts\
Step 3. Type //load -rs $qt($adiircdir\Scripts\fish_10.ini) and say yes to the popup dialog, if any.

Longer than 56 byte keys

To disable the max key length check and allow longer than 56 byte keys, run this command in the Editbox:

//dll $qt($adiircdir\Scripts\fish_10.dll) INI_SetBool enforce_max_key_length 0

The option should be saved across sessions.
