Use this method to check validity of the certificates received from the remote party in a time-stamping protocol (TSP) communication.
Use this method to validate the certificate received during timestamping (e.g., via OnCertificateValidate event of the TSP client). You need to pass the end-entity certificate only - CA certificates will be retrieved via Certificate's Chain property. So the event handler for OnCertificateValidate should look like this (in pseudocode):
If the chain is not available, you can pass CA certificates via AdditionalCertificates parameter or using AddKnownCertificates() method.
if (Certificate.Chain = null) or (Certificate.Chain.Certificates = Certificate) then Validator.ValidateForTimestamping(Certificate, …)
When CompleteChainValidation = true and the certificate is found to be not valid, certificate validation continues, i.e. issuer (CA) certificates are validated as well. This lets you create validation report which should include all certificates in the chain. When CompleteChainValidation = false and the certificate is not valid, further validation is not performed and Validate() method returns immediately.
Since version 13 ResetCertificateCache parameter has been replaced with ResetCertificateCache class method.
