OK, I'll commit a fix in a moment. The funny part, at least in SNAP,
is that the exact same condition exists in bn_mul_recursive() as well,
but with a cast that avoids the problem.

Hmm, do you have possibility to check what the IV becomes after you
initialise? And possibly what low-level function actually does the
encryption and decryption? If not, make some example code that we can
test with and send it to us.
phbgt> In the man, when you write EVP_CipherInit " always use the

If that's the meaning in practice, you've uncovered a bug.
