"Cracks" Event ID 1029 hashes, given a starting hash and a list of usernames
Thanks to reddit's /u/RedPh0enix and /u/Belgarion0 for basically everything.
They did all the hard work and figured out Microsoft's formatting.

Sample - Psudocode would be better spelled out as Base64(SHA256binary(UTF-16LE(UserName))
Event ID 1029 Description is Base64(SHA256(UserName)) is = UmTGMgTFbA35+PSgMOoZ2ToPpAK+awC010ZOYWQQIfc=-

Manual calculation of a hash can be done using the below:

import hashlib,base64
username = "ServerUser01"
username = username.decode('utf-8').encode('utf-16le')
hash = hashlib.sha256(username).digest() # note NOT .hexdigest()
print base64.b64encode(hash)
