CMP Protocol

CMP stands for Certificate Management Protocol, we are used specifications in RFC 4210, RFC 4211, and RFC 6712.

Certificate Management Protocol (CMP) Overview

The Certificate Management Protocol (CMP) is a standardized protocol for managing the lifecycle of digital certificates within a Public Key Infrastructure (PKI). It provides a secure and interoperable framework for requesting, generating, distributing, and revoking certificates. CMP is defined in RFC 4210, RFC 4211, and RFC 6712.

Supported Functionalities

CMP supports a wide range of functionalities to manage the lifecycle of certificates, including:

Initialization Request

The Initialization Request is used to initialize a new end-entity in the PKI. This involves generating a key pair for the end-entity and registering it with the PKI.

Certification Request

The Certification Request is used to request a new certificate for an existing PKI entity. This involves providing the PKI with the entity's public key and other relevant information, such as the entity's name and organization.

Key Update Request

The Key Update Request is used to request the replacement of an existing certificate with a new one. This is typically done when the key pair associated with the existing certificate expires or is compromised.

Certificate Confirmation

The Certificate Confirmation is used to confirm the receipt of a certificate. This is important for ensuring that the certificate was not tampered with during transmission.

Revocation Request

The Revocation Request is used to request the revocation of an existing certificate. This is typically done when the certificate is no longer valid, such as when it has been compromised or the entity associated with the certificate is no longer authorized to use it.
