So the database is encrypted by using AES-128-CBC or AES-128-CRT, right? Can I use AES-256-CBC?
No. Each tablespace is encrypted with a different per-tablespace key. This key is 128 bit. It's generated by encrypting a random 128-bit nonce with the user-specified key. So, if you specify a 256-bit key in the file_key_manager plugin, this 256-bit key will be used to generate the 128-bit tablespace key. The tablespace itself will be encrypted using the 128-bit key.
