Pwned Password

Fun project to utilize awesome ';--have i been pwned? Passwords API. It generates SHA1 hash for the password you provide as an argument and then grabs the range of hashes, basing on first 5 characters of the hash, from the service and checks if your hash is among them. So your password, nor its hash, never leaves your computer.

Usage is simple:

./pwned <password>

It'll print This is how many times your password was pwned: and a number if your password is in ';--have i been pwned? DB, else it'll print "Password not pwned!". Enjoy!
