PwnedPasswordsChecker is a tool that checks if the hash of a known password (in SHA1 or NTLM format) is present in the list of I Have Been Pwned leaks and the number of occurrences.
You can download the hash-coded version for SHA1 here or the hash-coded version for NTLM here
Once the list is downloaded it is then necessary to convert it to binary by using my other tool HIBP PasswordList Slimmer.
