perlgoon,

I've only used 'Crypt::OpenSSL::AES' and you create a cipher by passing an exact 32 byte string which is 256bits of data. After that de/encrypt is by passing the cipher and an exact 16 byte strings or 128 bits of data.

Also I use 'pack/unpack' to add the length of the actual string to the beginning of the encrypted data. This way you don't care if the data is a multiple of 16 bytes or not.

Note: As a side note, a few years ago several math minded scientists discovered that the original AES128 was more secure than AES256. You may want to google this to verify that this is still true.

Good Luck...Ed
