How to refresh the CRL cache on Windows Vista Random SSL/TLS 101 - OCSP/CRL in practice Detecting Certificate Authority compromises and web browser collusion immediately invalidate all items from the cache:Ĭertutil -setreg chain\ChainCacheResyncFiletime invalidate the currently cached items in 2 day, 4 hours(sets a registry value to the current date and time plus 2 days and 4 hour), basically disables temporarily the cache until after now plus 2 days and 4 hours:Ĭertutil -setreg chain\ChainCacheResyncFiletime identify the last time that the cache was invalidated(displays registry value):Ĭertutil -getreg chain\ChainCacheResyncFiletimeĬertutil -delreg chain\ChainCacheResyncFiletimeĬlearing the OCSP cache affects, as writing, browsers like IE and Chrome.Īlso the certutil command has an option(GUI) to verify the status of a certificate:Īdditionally you can check the validity of a certificate like:Ĭertutil -f –urlfetch -verify 'certificatefilename’ Instead of deleting you can invalidate the memory cache like so, set a expiry date for the CRL and OCSP cache(I did not mess too much with this one, sets a registry value to a specified date and time, the ChainCacheResynchFiletime value located in the HKLM\SOFTWARE\Microsoft\Cryptography\OID\EncodingType 0\CertDllCreateCertificateChainEngine\Config registry key the ChainCacheResynchFiletime value specifies the date and time to clear the in-memory cache): Speaking about Windows 7 or Windows Vista, you can view the OCSP or CRL cache with the certutil command like so(by default response caching is performed): The culprit Comodo CA has a somewhat smaller validity for its CRL and OCSP responses. OCSP stapling may help an attacker in certain cases. OCSP nonces were once used with Opera, but as far as I know most browsers currently do not use them. This means, that if your app does not “demand” a “fresh” CRL from the CA or a “fresh” OCSP response from the OCSP responder and is willing to accept for example a 5 days old OCSP response, everything is (almost) pretty useless. Note that even if you force a revocation check, or clear the OCSP/CRL cache, or use HSTS, or do 20 push ups, it may not really matter.įor example, looking at VeriSign you may notice that they date as valid for about a week OCSP responses and CRLs. Reading one or another related to the Comodo buzz, I was not surprised a bit.
