## Description

Passlib is a password hashing library for Python 2 & 3, which provides
cross-platform implementations of over 30 password hashing algorithms, as well
as a framework for managing existing password hashes. It's designed to be useful
for a wide range of tasks, from verifying a hash found in /etc/shadow, to
providing full-strength password hashing for multi-user applications.

## AI interpretation — verify before relying

Passlib provides cross-platform implementations of over 30 password hashing algorithms and a framework for managing password hashes, supporting tasks from verifying system shadow files to full-strength hashing for multi-user applications.

Verdict: Passlib remains a widely-used, dependency-free password hashing framework with permissive licensing, but its abandoned status since 2020-10-08 is a significant risk—no security updates and potential incompatibilities with modern systems. Use only in legacy systems or if you can actively maintain it.
