I get always the same output for debug / and the "different" same each time for the release, if I use the same key and the same input data. I'm using the following EVP_* functions: EncryptInit(), EncryptUpdate(), EncryptFinal(). Using the 3DES cbc algorithm, but I tried the blowfish too, with the same results. I assume I use the functions correctly, because they work in debug mode. I don't know what an "IV" is.
