Will implement and test later this week.</p> <p style="margin: 10px 0 0 0">It was making me uncomfortable to think of mucking around with the JSSE layer, e.g. trying to disable or invalidate the TLS session resumption feature. We don't necessarily want to do that. In fact ideally we'd want session resumption to still happen, because of the obvious TLS crypto efficiency advantages.</p> <p style="margin: 10px 0 0 0">All we really want is to ensure that our <tt>TrustEngine</tt> server TLS eval happens on every call and enforce the constraint/requirement that that implies.</p> <p style="margin: 10px 0 0 0">I think the right solution is to just make sure that it always runs, regardless of a full TLS handshake or an abbreviated handshake via session resumption. You may recall that prior to 4.0.0 we used to do the server TLS eval right in the <tt>SecurityEnhancedTLSSocketFactory</tt>, and only moved it to the <tt>X509TrustManager</tt> impl b/c of issues TLS renegotiation. This issue would not have manifested there because the trust engine eval always ran directly in the socket factory.</p> <p style="margin: 10px 0 0 0">What I think we should do is just check in <tt>SecurityEnhancedTLSSocketFactory</tt> whether it did already run in the JSSE layer, and if not, run it in the socket factory. So that ensures that it always runs exactly once per HTTP request. The test is simple: after socket connection (and handshake) if trust engine IS NOT null and if eval flag IS null. We'll just factor out the actual <tt>TrustEngine</tt> eval logic to a support class with appropriate overloaded methods, and then call that from both the socket factory and the X509 trust manager.</p> <p style="margin: 10px 0 0 0">I think that works and is much simpler and less invasive than trying to change the JSSE behavior itself.</p> </td>
