Classes

AsymmetricSignatureContext

finalize(self)


          Returns the signature as bytes.
        

update(self, data)


          Processes the provided bytes and returns nothing.
        

AsymmetricVerificationContext

update(self, data)


          Processes the provided bytes and returns nothing.
        

verify(self)


          Raises an exception if the bytes provided to update do not match the
          signature or the signature does not match the public key.
