Breaking 224-bit Blowfish encryption

Question

I have a bunch of encrypted files that I want to decrypt (duh). I found out they are encrypted with Blowfish using a 224-bit key after some research. I know what the first f

Answer 1

No, you can't recover the plain text unless the encryption was done incorrectly.

There is a published "known plain text" attack, but it requires billions of known plain texts to work.

Update regarding "Edit": Again, if the encryption was done correctly, examining the known keys won't help, because a cryptographic number generator used to generate good keys is going to have similar complexity as the cipher. However, using a bad generator (or password-based encryption with weak passwords) is a common implementation flaw. Good luck!
