Abstract

   This document specifies a protocol useful in determining the current
   status of a digital certificate without requiring CRLs. Additional
   mechanisms addressing PKIX operational requirements are specified in
   separate documents. This document obsoletes RFC 2560 and RFC 6277,
   and updates RFC 5912.
