Classes

AsymmetricPadding

name = <abc.abstractproperty object at 0x7f92bf0d0d00>

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

AsymmetricSignatureContext

finalize(self) -> bytes


          Returns the signature as bytes.
        

update(self, data: bytes) -> None


          Processes the provided bytes and returns nothing.
        

AsymmetricVerificationContext

update(self, data: bytes) -> None


          Processes the provided bytes and returns nothing.
        

verify(self) -> None


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

InvalidSignature

with_traceback(...)
