Package Cryptodome :: Package Hash :: Module SHA224

Module SHA224

SHA-224 cryptographic hash algorithm.

SHA-224 belongs to the SHA-2 family of cryptographic hashes. It produces the 224 bit digest of a message.

>>> from Cryptodome.Hash import SHA224
>>>
>>> h = SHA224.new()
>>> h.update(b'Hello')
>>> print h.hexdigest()

SHA stands for Secure Hash Algorithm.

Function Details

new(data=None)

 
Return a fresh instance of the hash object.
Parameters:
  • data (byte string) - The very first chunk of the message to hash. It is equivalent to an early call to SHA224Hash.update(). Optional.
Returns:
A SHA224Hash object
