Note that if you do this, you must hard-code the key somewhere (unless you are prompting the user for it) which means you are simply obfuscating the data, not actually encrypting it. > One of three things happens when I do this however. > > 1) Everything works fine. > 2) I cannot insert the encrypted string. > 3) The encrypted string is inserted, but incorrectly and will not > decrypt. > > I tried using a blob or medium blob for the datatype, but neither will > work 100% of the time.

Alternatively, it is probably of fixed size and so you could just store the resulting chunk of data as a series of 8 bit values. Note that if you do not need to be able to recover the password, just verify whether the password a user typed is correct, you CAN and, in fact, SHOULD use a one-way hash instead of an encryption. --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
