    abstract =  {This document proposes to extend the HTTP Digest Authentication by adding a set new algorithms. These algorithms use different hash functions and combination of various information such as user name, realm, password, salt, and/or other data, in order to achieve compatibility with existing mechanisms used to store user credentials in various authentication/autorization servers.},
