This commit updates the encryption logic to correctly use the secret key and initialization vector (IV) as separate components, rather than combining them into a single `Key` object. - The `Key` inline class now only holds the secret key bytes. - Encryption now returns a `Pair` containing the encrypted data (`Encrypted`) and the generated IV (`ByteArray`). - Decryption requires both the `Key` and the IV as input. - The `AuthenticationEntity` is updated to store the encrypted password and its corresponding IV separately. - The encryption test suite is updated to reflect these changes and includes a test for decryption with an incorrect IV.
