The Public-Key Infrastructure (X.509) (pkix) Working Group in the Security Area has concluded. The IESG contact persons are Stephen Farrell and Sean Turner. The PKIX working group has completed its charter items, and is officially closing. The mailing list will be retained for future discussions. The PKIX working group was focused on PKI (Public Key Infrastructure) standards. Over its 18 year existence, the working group published over 70 with the most prominent being RFC 2459/3280/5280: the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile. Other notable work includes RFC 6960: OCSP (Online Certificate Status Protocol), RFC 4210: CMP (Certificate Management Protocol), RFC 5272: CMC (Certificate Management over Certificate Management Syntax), and RFC 7030: EST (Enrollment over Secure Transport). The RFCs produced by the WG are the underpinning of many protocols that secure the Internet at almost every layer of the protocol stack. Both Stephen and I would like to thank all of the IETF participants who have contributed to documents produced by the PKIX working group and to the successful completion of these important deliverables. We especially thank Warwick Ford, Tim Polk, and Stefan Santesson who chaired the working group at various time since its formation as well as Steve Kent who chaired the working group since its inception.
