Classes

AlreadyFinalized

with_traceback(...)

  Exception.with_traceback(tb) --
      set self.__traceback__ to tb and return self.

args = <attribute 'args' of 'BaseException' objects>

InvalidKey

with_traceback(...)

  Exception.with_traceback(tb) --
      set self.__traceback__ to tb and return self.

args = <attribute 'args' of 'BaseException' objects>

KeyDerivationFunction

derive(self, key_material: bytes) -> bytes


          Deterministically generates and returns a new key based on the existing
          key material.

verify(self, key_material: bytes, expected_key: bytes) -> None


          Checks whether the key generated by the key material matches the
          expected derived key. Raises an exception if they do not match.

Scrypt

derive(self, key_material: bytes) -> bytes

verify(self, key_material: bytes, expected_key: bytes) -> None

ScryptBackend

derive_scrypt(self, key_material, salt, length, n, r, p)


          Return bytes derived from provided Scrypt parameters.

UnsupportedAlgorithm

with_traceback(...)

  Exception.with_traceback(tb) --
      set self.__traceback__ to tb and return self.

args = <attribute 'args' of 'BaseException' objects>
