Sign and verify functions
Arguments
| :: HashAlgorithm hash | |
| => ByteString | Salt to use |
| -> Maybe Blinder | optional blinder to use |
| -> PSSParams hash ByteString ByteString | PSS Parameters to use |
| -> PrivateKey | RSA Private Key |

Sign using the PSS Parameters
Arguments
| :: (HashAlgorithm hash, MonadRandom m) | |
| => PSSParams hash ByteString ByteString | PSS Parameters to use |
| -> PrivateKey | private key |
| -> ByteString | message to sign |
| -> m (Either Error ByteString) |
Sign using the PSS Parameters and an automatically generated blinder.
Arguments
| :: HashAlgorithm hash | |
| => PSSParams hash ByteString ByteString | PSS Parameters to use to verify, this need to be identical to the parameters when signing |
| -> PublicKey | RSA Public Key |
| -> ByteString | Message to verify |
| -> ByteString | Signature |
| -> Bool |
Verify a signature using the PSS Parameters
