Well, they might have done this *knowingly*, but--at least for some--I doubt that they *know* what they have done. IMO, it is bad practice to implement only half of a protocol/standard for any reason (especially out of laziness or ignorance), but that is what using certificates without CRL checking amounts to.On 8-Aug-08, at 10:11 AM, Ben Laurie wrote:It also only fixes this single type of key compromise. Surely it is time to stop ignoring CRLs before something more serious goes wrong?Clearly many implementors have chosen to *knowingly* ignore CRLs despite the security implications, so my take away would be that the current public key infrastructure is flawed.
If we believe that the current PKI was truly flawed, it would be an act of gross negligence to use it for anything requiring a properly secured communication channel.
To extend Ben's advice: Decide if you want to use the current PKI. If so, implement CRL checking.
