Question

I tried this code:

import hashlib
encrypted = hashlib.sha1(string)
encrypted = encrypted.digest()

But I got an error that says "No Module Named hashlib". What is wrong, and how do I fix it?

Answer 1

You’ve probably got a python version < 2.5. Use the sha module instead.

Here’s the differences:

>>> import sha
>>> s = sha.new()
>>> s.update('hello')
>>> s.digest()
'\xaa\xf4\xc6\x1d\xdc\xc5\xe8\xa2\xda\xbe\xde\x0f;H,\xd9\xae\xa9CM'

vs

>>> import hashlib
>>> hashlib.sha1('hello').digest()
'\xaa\xf4\xc6\x1d\xdc\xc5\xe8\xa2\xda\xbe\xde\x0f;H,\xd9\xae\xa9CM'
