2.20 The sha Module

The sha module provides an alternative way to calculate message signatures, as shown in Example 2-39. It's similar to the md5 module, but generates 160-bit signatures instead.

Example 2-39. Using the sha Module

File: sha-example-1.py

import sha

hash = sha.new()
hash.update("spam, spam, and eggs")

print repr(hash.digest())
print hash.hexdigest()

'\321\333\003\026I\331\272-j\303\247\240\345\343Tvq\364\346\311'

See the md5 examples for more ways to use sha signatures.
