Technical Summary
 
   Use of the Domain Name System TSIG resource record requires
   specification of a cryptographic message authentication code.
   Currently identifiers have been specified only for the HMAC MD5
   (Message Digest) and GSS (Generic Security Service) TSIG algorithms.
   This document standardizes identifiers and implementation
   requirements for additional HMAC SHA (Secure Hash Algorithm) TSIG
   algorithms and standardizes how to specify and handle the truncation
   of HMAC values in TSIG.
 
Working Group Summary
