This document defines a new encryption type and a new checksum type for use with Kerberos V5 [RFC1510]. This encryption type is based on the Triple DES cryptosystem and the HMAC-SHA1 [Krawczyk96] message authentication algorithm. The des3-cbc-hmac-sha1 encryption type has been assigned the value 7. The hmac-sha1-des3 checksum type has been assigned the value 12.
