Detailed Description

Provides authentication via a message authentication codes (MAC).

This node provides a service call that can be used to authenticate a user to use the ROS server. The node relies on a hash string that is made up of several pieces of information and hashed using the SHA-1 algorithm. This node is based on the best-practice method of a message authentication codes (MAC).
