MySQL Error 1882: Invalid AES IV Length
Description
This error indicates that an Initialization Vector (IV) supplied to an AES encryption or decryption function in MySQL is shorter than the minimum required length. This prevents the cryptographic operation from proceeding securely and correctly, often leading to data processing failures.
Error Message
The initialization vector supplied to %s is too short. Must be at least %d bytes long
Known Causes
3 known causesIncorrect IV Generation
The application or client code generating or supplying the Initialization Vector (IV) creates one that does not meet the minimum byte length required by the MySQL AES function.
AES Function Misconfiguration
The specific AES function being called expects an IV of a certain minimum length, but the provided IV parameter is consistently too short due to a misunderstanding of the function's requirements.
IV Data Truncation
The Initialization Vector might have been generated correctly but was truncated during storage in a database field or transmission, resulting in a shortened value when retrieved for use.
