HTTP Hawk Authentication Scheme

Hawk is a Node.js library implementing the HTTP Hawk Authentication Scheme, a robust mechanism for making authenticated HTTP requests with partial cryptographic verification. It uses a message authentication code (MAC) algorithm to cover the HTTP method, request URI, host, and optionally the request payload, providing an alternative to HTTP Digest access authentication. Developed by Mozilla, the package is currently at version 9.0.2. It is in a 'maintenance mode' where no new features are added, and only security-related bug fixes are applied, with v9.0.2 announced as the final release. Key differentiators include its focus on two-legged client-server authentication (not OAuth delegation) and its history of ownership by hueniverse, then @hapi, and now Mozilla.
