2.17. New Section 5.3.19.17 - CRL Update Retrieval​

The following subsection introduces the PKI general message using id-it-crlStatusList and id-it-crls. Details are specified in Section 4.3 of the Lightweight CMP Profile [RFC9483]. Insert this section after the new Section 5.3.19.16:

5.3.19.17. CRL Update Retrieval​

This MAY be used by the client to get new CRLs, specifying the source of the CRLs and the thisUpdate value of the latest CRL it already has, if available. A CRL source is given either by a DistributionPointName or the GeneralNames of the issuing CA. The DistributionPointName should be treated as an internal pointer to identify a CRL that the server already has and not as a way to ask the server to fetch CRLs from external locations. The server shall only provide those CRLs that are more recent than the ones indicated by the client.

GenMsg:    {id-it 22}, SEQUENCE SIZE (1..MAX) OF CRLStatus
GenRep:    {id-it 23}, SEQUENCE SIZE (1..MAX) OF
                         CertificateList  |  < absent >
CRLSource ::= CHOICE {
   dpn          [0] DistributionPointName,
   issuer       [1] GeneralNames }

CRLStatus ::= SEQUENCE {
   source       CRLSource,
   thisUpdate   Time OPTIONAL }
