Mandatory OCSP is security theater? That’s a pretty bold claim.

Mandatory OCSP that fails open when you're offline is security theater.

  • OCSP fails open by definition because it is a revocation protocol. In the absence of revocation, a valid cert continues to be valid.

    The problem here is simply that Apple did not build a short enough timeout into their client.
