SHA3-512

SHA3-512 belongs to the SHA-3 family of cryptographic hashes, as specified in FIPS 202.

The hash function produces the 512 bit digest of a message:

>>> from Crypto.Hash import SHA3_512
>>>
>>> h_obj = SHA3_512.new()
>>> h_obj.update(b'Some data')
>>> print h_obj.hexdigest()

SHA stands for Secure Hash Algorithm.

class Crypto.Hash.SHA3_512.SHA3_512_Hash(data, update_after_digest)

A SHA3-512 hash object. Do not instantiate directly. Use the new() function.

Variables:
  • oid (string) – ASN.1 Object ID
  • digest_size (integer) – the size in bytes of the resulting hash
digest()

Return the binary (non-printable) digest of the message that has been hashed so far.

Returns:The hash digest, computed over the data processed so far. Binary form.
Return type:byte string
hexdigest()

Return the printable digest of the message that has been hashed so far.

Returns:The hash digest, computed over the data processed so far. Hexadecimal encoded.
Return type:string
new()

Create a fresh SHA3-512 hash object.

update(data)

Continue hashing of a message by consuming the next chunk of data.

Parameters:data (byte string/byte array/memoryview) – The next chunk of the message being hashed.
Crypto.Hash.SHA3_512.new(*args, **kwargs)

Create a new hash object.

Parameters:
  • data (byte string/byte array/memoryview) – The very first chunk of the message to hash. It is equivalent to an early call to update().
  • update_after_digest (boolean) – Whether digest() can be followed by another update() (default: False).
Return:

A SHA3_512_Hash hash object
