Internet Engineering Task Force (IETF) S. Lawrence Request for Comments: 5924 Category: Experimental V. Gurbani ISSN: 2070-1721 Bell Laboratories, Alcatel-Lucent June 2010 Extended Key Usage (EKU) for Session Initiation Protocol (SIP) X.509 Certificates Abstract This memo documents an extended key usage (EKU) X.509 certificate extension for restricting the applicability of a certificate to use with a Session Initiation Protocol (SIP) service. As such, in addition to providing rules for SIP implementations, this memo also provides guidance to issuers of certificates for use with SIP.
