How to calculate NTLM hash in python?

Question

How can I calculate NTLM hash of a passowrd in python? Is there any library or sample code?

I want it for writing a NTLM brute force tools with python (Like Cain & Abel )

Solution

You can make use of the hashlib and binascii modules to compute your NTLM hash:

import binascii, hashlib
input_str = "SOMETHING_AS_INPUT_TO_HASH"
ntlm_hash = binascii.hexlify(hashlib.new('md4', input_str.encode('utf-16le')).digest())
print ntlm_hash

why not this? pythonhosted.org/passlib/lib/passlib.hash.nthash.html not familiar with NTLM hash at already.

passlib is a separate python package, but binascii and hashlib are part of the standard python library. Not saying you should not use passlib, it is upto the author's preference. There are other libraries as well like python-ntlm.

Thanks. interesting how OP checked the other guy. He just copy and paste from an online source code and you being the first one didn't get checked.
