Certificate Management over CMS (CMC)
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.
Abstract
This document defines the base syntax for CMC, a Certificate
Management protocol using the Cryptographic Message Syntax (CMS).
This protocol addresses two immediate needs within the Internet
Public Key Infrastructure (PKI) community:
1. The need for an interface to public key certification products
and services based on CMS and PKCS #10 (Public Key Cryptography
Standard), and
2. The need for a PKI enrollment protocol for encryption only keys
due to algorithm or hardware design.
CMC also requires the use of the transport document and the
requirements usage document along with this document for a full
definition.
