binarylogic/authlogic
Authlogic is a Ruby authentication library that provides session management, password hashing, and user validation for Rails, Rack, and Sinatra applications. It replaces the legacy Authgasm codebase with a modernized architecture featuring pluggable crypto providers, case-sensitive query handling, and comprehensive testing utilities. The system supports multiple database backends and enforces security best practices through configurable session and authentication behaviors.
