setup: use modern bcrypt implementation instead of unsupported old one py-bcrypt has been deprecated by bcrypt, and is no longer developed or supported. bcrypt requires bytestrings instead of strings, use safe_str to ensure they're encoded before they're passed to bcrypt. Also, use check_pw to minimise the number of manual conversions and comparisons. Installation of bcrypt will probably compile a C extension and require libffi-dev.
