Quick binary search for NTLM hash dataset

PwnedPasswordsNTLM

Basic binary search on a sorted file containing NTLM hashes from Pwned Passwords or any set of NTLM hashes. Iterates line by line over an input file, conducts a binary search over the dataset to search for the hash in the current line. Outputs to file a list of users with breached passwords.

Note: requires that the input file be in Hashcat format (Username:Hash).

For more details on how to extract the hashes, and further background, please see my post here - http://jacksonvd.com/pwned-passwords-and-ntlm-hashes

pwnedpasswordsntlm's Issues

Not all hashes are found, error in search routine

I created a similar PowerShell script that runs not as fast as this program here, but I had in our Test-Set detected ~1600 matches in comparison to ~600 matches with your code. I think that the changes to the code to work with the extended format that includes the occurrences messed up the function of your code.
