Additional mechanisms addressing PKIX operational requirements are specified in separate documents.
This specification is part of a multi-part standard for the Internet Public Key Infrastructure (PKI) using X.509 certificates and certificate revocation lists (CRLs). This document specifies the conventions for using the File Transfer Protocol (FTP) and the Hypertext Transfer Protocol (HTTP) to obtain certificates and CRLs from PKI repositories. Additional mechanisms addressing PKI repository access are specified in separate documents.
