Multiple entries may be listed. An OCSP responder provides immediate and accurate revocation information on specific certificates as follows:. A default version of the configuration file can be used for reference purposes to view new available options.
For added security to avoid replay attacks , an OCSP requester can add a nonce to the certificate validation request. A nonce is a random number, attached to each request, that alters the encryption. When the nonce feature is enabled, the OCSP responder computes an appropriate response using the nonce value. Note Using a nonce puts more load on the OCSP responder because it cannot precalculate or cache responses.
