Password policy enforcement for Java

Passay builds on the success of vt-password and provides a comprehensive and extensible feature set.

Password validation

Enforce password policy by validating candidate passwords against a configurable rule set. Passay provides a comprehensive set of rules for common cases and supports extension through a simple rule interface.

Password generation

Generate passwords using a configurable rule set. The password generator is extensible like all Passay components.

Command line tools

History

Passay is the descendant of the venerable vt-password Java library produced by the Middleware group at Virginia Tech. Passay builds on the lessons learned from vt-password, which was well-regarded in its own right. Passay is more convenient, more extensible, and ready for internationalization.
