I've been doing some tests with this tool : http://crypto.hurlant.com/demo/CryptoDemo.swf and been trying to match blowfish results obtained from Mirc + blowfish (from what used to be fish.secure.us v1.30). I cannot for the life of me find what mode it is using... Nothing matches.. Does anyone know what mode it uses ??
It simply uses ECB mode, but the base64 encoding is done in an odd way - each block of 32 bits of ciphertext is independently encoded into 6 base64 characters.
