passpwn - password breach checker

This is a tool for checking your passwords in pass against Have I been pwned?.

passpwn uses the range API which means that we are only sending the first 5 characters of a SHA1 hashed password to Have I been pwned? and are checking the returned hashes against the full local hash.

Inspiration for this tool comes from the 1Password blog.

A big thanks to for making this possible in a secure way.
