Abstract

A method, an apparatus, a system, and a computer program product are presented for validating certificates. A certificate validation service receives a certificate validation request for a target certificate from a client, thereby allowing the client to offload certificate validation tasks into an online certificate validation service that is accessible and sharable by multiple components within a data processing system. In response to a determination that the target certificate is valid or invalid, the certificate validation service sends a certificate validation response with an indicating status value that the target certificate is valid or invalid. The certificate validation service is able to cache information about previously validated certificates and the associated certificate chains, thereby enhancing the efficiency of the service. Different certificate validation policies may be applied against target certificates based upon information associated with the target certificates.
