From: Dr. Stephen Henson Date: Wed, 26 Dec 2012 14:26:16 +0000 (+0000) Subject: Reorganise supported signature algorithm extension processing. X-Git-Tag: OpenSSL_1_0_2-beta1~525 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c70a1fee71119a9005b1f304a3bf47694b4a53ac;p=oweals%2Fopenssl.git Reorganise supported signature algorithm extension processing. Only store encoded versions of peer and configured signature algorithms. Determine shared signature algorithms and cache the result along with NID equivalents of each algorithm.
