MySQL Error 3235: Invalid KDF Method Name
Description
This error indicates that MySQL encountered an unsupported or incorrect Key Derivation Function (KDF) method name during an operation requiring key derivation, such as encryption or password hashing. It specifically instructs the user to use 'hkdf' or 'pbkdf2_hmac' as valid methods. This typically occurs when configuring encryption parameters or executing SQL functions that rely on KDFs.
Error Message
KDF method name is not valid. Please use hkdf or pbkdf2_hmac method name
Known Causes
3 known causesIncorrect KDF in Configuration File
A Key Derivation Function method other than 'hkdf' or 'pbkdf2_hmac' is specified in MySQL's configuration (e.g., `my.cnf`/`my.ini`) for encryption-related settings.
Invalid KDF in SQL Statement
An SQL function or statement that requires a KDF (e.g., `AES_ENCRYPT`, `AES_DECRYPT` with KDF options, or keyring operations) has been called with an unsupported method name.
Typo or Case Mismatch
The specified KDF method name contains a spelling error or incorrect capitalization, preventing MySQL from recognizing 'hkdf' or 'pbkdf2_hmac'.
