getCrypt() pads the backup password with "x" characters and cuts it to 32 bytes to form the AES key, with no salt and no key derivation. The first block of a backup holds a 16 hex digit length field, so decrypting one block confirms a password guess at raw AES speed.
An attacker who obtains a backup can recover its password by fast offline guessing, and with it every credential the backup holds.
