Posted by developer: The referenced documentation has been updated as follows: "Advanced Encryption Standard (AES) is the only supported encryption algorithm. InnoDB tablespace encryption uses Electronic Codebook (ECB) block encryption mode for tablespace key encryption and Cipher Block Chaining (CBC) block encryption mode for data encryption. Padding is not used with CBC block encryption mode. Instead, InnoDB ensures that the text to be encrypted is a multiple of the block size." The change should appear online soon. Thank you for the bug report.
