Package Crypto :: Package Hash :: Module SHA

Module SHA

SHA-1 cryptographic hash algorithm.

SHA-1 produces the 160 bit digest of a message.

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

SHA stands for Secure Hash Algorithm.

This algorithm is not considered secure. Do not use it for new designs.

Classes
	SHA1Hash Class that implements a SHA-1 hash

Functions

new(data=None)
Return a fresh instance of the hash object.

Variables
	digest_size = `20` The size of the resulting hash in bytes.

Function Details

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 SHA1Hash.update(). Optional.

Returns:

A SHA1Hash object
