ocspd(1)                  BSD General Commands Manual                 ocspd(1)

NAME
     ocspd -- OCSP and CRL Daemon

SYNOPSIS
     ocspd

DESCRIPTION
     ocspd performs caching and network fetching of Certificate Revocation Lists (CRLs) and Online Certifi-cate Certificate
     cate Status Protocol (OCSP) responses. It is used by Security.framework during certificate verifica-tion. verification.
     tion. Security.framework communicates with ocspd via a private RPC interface. When Security.framework
     determines that a CRL is needed, or that it needs to perform an OCSP transaction, it performs an RPC to
     ocspd which then examines its cache to see if the appropriate CRL or OCSP response exists and is still
     valid. If so, that entity is returned to Security.framework. If no entry is found in cache, ocspd
     obtains it from the network, saving the result in cache before returning it to Security.framework.

     This command is not intended to be invoked directly.
