deriveKeyFromPasswordBytes abstract method
Derives a key from password bytes and salt.
passwordBytes should be UTF-8 encoded password bytes.
salt is the cryptographic salt.
userIdBytes is optional - when provided, will be prepended as
"userId:password" per RFC 5054 specification.
Implementation
Future<Uint8List> deriveKeyFromPasswordBytes({
required Uint8List passwordBytes,
required Uint8List salt,
Uint8List? userIdBytes,
});
