From 172b2beba6b89b632c09be7a88645e3a0607cfe9 Mon Sep 17 00:00:00 2001 From: Jay Satiro Date: Fri, 17 Jul 2015 02:40:16 -0400 Subject: SSL: Add an option to disable certificate revocation checks New tool option --ssl-no-revoke. New value CURLSSLOPT_NO_REVOKE for CURLOPT_SSL_OPTIONS. Currently this option applies only to WinSSL where we have automatic certificate revocation checking by default. According to the ssl-compared chart there are other backends that have automatic checking (NSS, wolfSSL and DarwinSSL) so we could possibly accommodate them at some later point.
