RT @lightcoin: “Some CAs are saving OCSP requests and selling that [customer] data.” - @ChristopherA #SSL #TLS #privacy

.@lightcoin To be precise, OCSP requires verification by the client, which is easily tracked and info could be sold. I don’t know if it is.

Wed Jun 03 19:55:45 +0000 2015

.@lightcoin Today OCSP is broken, as browsers don’t report OCSP errors by default. Also OCSP Stapling is used for fewer validation requests.

Replying to @lightcoin

I have heard that was true, but don’t know that it is true today.

Wed Jun 03 22:17:18 +0000 2015

Agreed, OCSP Stapling is the best practice today. But it is still a hack and doesn’t really solve the problem. https://twitter.com/ECCTLS/status/606189302901436416

Replying to @yuhong2, @lightcoin and @BRIAN_____

Do you have a link for that? The report I saw only talked about the certs compromised, not OCSP data.
