This specification defines a profile of the Online Certificate Status
Protocol (OCSP) that addresses the scalability issues inherent when
using OCSP in large scale (high volume) Public Key Infrastructure
(PKI) environments and/or in PKI environments that require a
lightweight solution to minimize communication bandwidth and client-
side processing.
This specification obsoletes RFC 5019. The profile specified in RFC
5019 has been updated to allow and recommend the use of SHA-256 over
SHA-1.
