From the DISQLite3.chm documentation:
function sqlite3_rekey(
DB: sqlite3_ptr;
const PKey: C_char_ptr;
nKey: C_int
): C_int;
Change the key on an open database. If the current database is
not encrypted, this routine will encrypt it. If PKey=nil or
nKey=0, the database is decrypted.
Please note that decryption does not work with a SHA-256 hex key. It
works by opening the database with the password used to encrypt it and
then calling the above function as described.

The 2nd in your list.
