Overview
 

The purpose of this project is to create a freely available library that can be easily adopted by most MTA and UA implementers to add DomainKeys (Historical RFC 4870) functionality. DKIM is the Standards Track RFC for email authentication. DKIM.org is actively maintained suporting the adoption of DomainKeys Identified Mail.

The DomainKeys Library was written in C and provided a foundation for implementing the DomainKeys email authentication system in mail transfer agents and mail user agents.
