Classes

AlreadyFinalized

with_traceback(...)

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

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

ExtendableOutputFunction

    An interface for extendable output functions.
    

Hash

copy(self) -> 'Hash'

finalize(self) -> bytes

update(self, data: bytes) -> None

algorithm = <property object at 0x7f02272428b0>

HashAlgorithm

block_size = <abc.abstractproperty object at 0x7f0227246c40>

          The internal block size of the hash function, or None if the hash
          function does not use blocks internally (e.g. SHA3).
        

digest_size = <abc.abstractproperty object at 0x7f0227246ac0>

          The size of the resulting digest in bytes.
        

name = <abc.abstractproperty object at 0x7f022722ed60>

          A string naming this algorithm (e.g. "sha256", "md5").
        

HashBackend

create_hash_ctx(self, algorithm)


          Create a HashContext for calculating a message digest.
        

hash_supported(self, algorithm)


          Return True if the hash algorithm is supported by this backend.
        

HashContext

copy(self) -> 'HashContext'


          Return a HashContext that is a copy of the current context.
        

finalize(self) -> bytes


          Finalizes the hash context and returns the hash digest as bytes.
        

update(self, data: bytes) -> None


          Processes the provided bytes through the hash.
        

algorithm = <abc.abstractproperty object at 0x7f022724f340>

          A HashAlgorithm that will be used by this context.
