The Validation Server provides OCSP validation based on multiple sources. It consists of a server application handling
the validation requests and an administration application for the configuration of the server application. Depending on
the chosen deployment, both applications run on the same server or on different machines.

The Validation Server is a modularly built OCSP V1 (RFC 2560) conform responder for the online validation of
certificates. OCSP V1 compatible clients can send OCSP V1 requests to the server to verify the status of a certificate
without having to use client side CRLs. The Validation Server fulfills all MUST criteria described in RFC 2560.

In addition to RFC 2560, the Validation Server also supports *The Lightweight Online Certificate Status Protocol
(OCSP) Profile for High-Volume Environments* according to RFC 5019.
