RsaPss class abstract

RSA-PSS SignatureAlgorithm.

In browsers, the default implementation will use Web Cryptography API. On other platforms, DartRsaPss will be used.

Private keys must be instances of RsaKeyPair. Public keys must be instances of RsaPublicKey.

You can use package:jwk to encode/decode JSON Web Key (JWK) data.

Example

import 'package:cryptography/cryptography.dart';

Future<void> main() async {
  final algorithm = RsaPss(Sha256());

  // Generate a key pair
  final keyPair = await algorithm.newKeyPair();

  // Sign a message
  final message = <int>[1,2,3];
  final signature = await algorithm.sign(
    message,
    keyPair: keyPair,
  );
  print('Signature bytes: ${signature.bytes}');
  print('Public key: ${signature.publicKey.bytes}');

  // Anyone can verify the signature
  final isSignatureCorrect = await algorithm.verify(
    message,
    signature: signature,
  );
}
