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.

How it got here

2008 · Authgasm to Authlogic migration

The project underwent a major rebranding and refactoring, renaming from Authgasm to Authlogic and updating the gem's entry point and namespace. This period focused on modernizing the codebase by consolidating session management, adding support for non-Rails frameworks like Rack and Sinatra, and introducing new cryptographic providers such as SCrypt.
