Re: blowfish from openSSL to kernel cryptoAPI

I was assuming that given the same parameters (e.g. encryption algorithm, CBC, key, iv), the cipher data would be equivalent between different implementations (in this case openSSL/cryptoapi). Was that a wrong assumption?

Are the implementations incompatible (i.e. can't encrypt in one and decrypt in the other?) or am I doing something wrong?Check byte order of the two implementations. Many blowfish implementations got byte order wrong. Does it help if you swap byte order from 0-1-2-3-4-5-6-7 to 7-6-5-4-3-2-1-0 of key/data/IV before and after crypto operation?
