SUMMARY = "comprehensive password hashing framework supporting over 30 schemes"

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.

* See the `documentation <https://passlib.readthedocs.io>`_
  for details, installation instructions, and examples.

* See the `homepage <https://bitbucket.org/ecollins/passlib>`_
  for the latest news and more information.

* See the `changelog <https://passlib.readthedocs.io/en/stable/history>`_
  for a description of what's new in Passlib.
