Description:
aes_encrypt/aes_decrypt works correctly for a test case. Change only
the last two digits of the string needing to be encrypted and
it returns null.
I formed the queries below by cut and paste, so I was sure that the
password was constant. The actual problem occured when my C program,
using a server side password that was not altered during execution,
would work correctly for 55 insert statements and have an error on one.
As I was about to send this, I repeated the test except for changing
the key to gary. Everything worked then.
Linux/Red Hat Version 8.0
