RSA Security 5 manual Input constraints

AI_DESX_CBC_BSAFE1

Input constraints:

During encryption, this algorithm does not pad the output. Thus, you must provide input that is a multiple of 8 bytes.

Output considerations:

In pad mode, the total number of output bytes from encryption can be as many as 8 more than the total input. In pad with checksum mode, the total number of output bytes from encryption can be as many as 16 more than the total input.
