David,
It has no way of knowing whether the "password" or "key" you provided is "the right one." Encryption and Decryption is just a mathematical transformation of the data ... using one of several algorithms, such as AES ...
So, if you give it the wrong key, "Garbage In, Garbage Out."
Welcome to the wild and wooly world of encryption. :-)
Enjoy.

My gut says I'm missing something...
For compatibility sake, I'm running on 7.2.
I'm encrypting data in a char column (for bit data) using the SQL
ENCRYPT_AES function.
I use the DECRYPT_CHAR function to decrypt it.
If I use the correct password, it decrypts fine.
If I use the wrong password, it does not fail. SQLCOD and SQLSTATE are
both 0. The returned value is garbage.
Shouldn't the decrypt function, with a wrong password, set an error code?
