This module has no docstring.

Classes

AsymmetricPadding

name = <abc.abstractproperty object at 0x7f0567681a00>

          A string naming this padding (e.g. "PSS", "PKCS1").
        

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.
