3.1 Certification request

3.1 Certification request

A certification request is an RFC 1421 MIC-ONLY or MIC-CLEAR privacy-enhanced message containing a self-signed certificate. There is only one signer.

The fields of the self-signed certificate (which has type Certificate, as in RFC 1422) are as follows:

The requestor's MIC encryption algorithm must be asymmetric (e.g., RSA) and the MIC algorithm must be keyless (e.g., RSA-MD2, not MAC), so that anyone can verify the signature.

Example:

   To: cert-service@ca.domain
   From: requestor@host.domain

   -----BEGIN PRIVACY-ENHANCED MESSAGE-----
   Proc-Type: 4,MIC-ONLY
   Content-Domain: RFC822
   Originator-Certificate: <requestor's self-signed certificate>
   MIC-Info: RSA,RSA-MD2,<requestor's signature on text>

   <text>
   -----END PRIVACY-ENHANCED MESSAGE-----
