SHA-224¶
SHA-224 belongs to the SHA-2_ family of cryptographic hashes. It produces the 224 bit digest of a message.
>>> from Crypto.Hash import SHA224
>>>
>>> h = SHA224.new()
>>> h.update(b'Hello')
>>> print h.hexdigest()
SHA stands for Secure Hash Algorithm.

- class Crypto.Hash.SHA224.SHA224Hash(data=None)¶
Class that implements a SHA-224 hash
- Undocumented:
block_size
- new(data=None)¶
Return a fresh instance of the hash object.
Unlike the copy method, the internal state of the object is empty.
- Parameters:
- databyte string
The next chunk of the message being hashed.
- Return:
A hash object of the same type
- oid = b'\x06\t`\x86H\x01e\x03\x04\x02\x04'¶
ASN.1 Object identifier (OID):
id-sha224 OBJECT IDENTIFIER ::= { joint-iso-itu-t(2) country(16) us(840) organization(1) gov(101) csor(3) nistalgorithm(4) hashalgs(2) 4 }
This value uniquely identifies the SHA-224 algorithm.
- Crypto.Hash.SHA224.digest_size = 28¶
The size of the resulting hash in bytes.
- Crypto.Hash.SHA224.new(data=None)¶
Return a fresh instance of the hash object.
- Parameters:
- databyte string
The very first chunk of the message to hash. It is equivalent to an early call to SHA224Hash.update(). Optional.
- Return:
A SHA224Hash object
