-Subject: [PATCH] OpenSSL: deselect weak ciphers by default
-
-By default even recent versions of OpenSSL supports and accepts both
-"export strength" ciphers, small-bitsize ciphers as well as downright
-deprecated ones.
-
-This change sets a default cipher selection that tries to avoid the
-worst ones, and subsequently it makes https://www.howsmyssl.com/a/check
-no longer grade curl/OpenSSL connects as 'Bad'.
-
-Bug: http://curl.haxx.se/bug/view.cgi?id=1323
-Reported-by: Jeff Hodges
-
-(Note that we have an older version of curl, and the required changes need
-to be made to .../lib/ssluse.[c,h] not .../lib/vtls/openssl.[c,h].)
