Subject: Allow forced setting of TLS1.1 and TLS1.2 protocols with
X-Git-Tag: 2.5.0-alpha~6228
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c2b7802e781264ae1f1107e0b2d68ac5d63783fb;p=thirdparty%2Fapache%2Fhttpd.git

Allow forced setting of TLS1.1 and TLS1.2 protocols with
the -f command-line switch, and adapt the output to more accurately
report what SSL/TLS protocol was negotiated (use SSL_get_version()
instead of SSL_CIPHER_get_version()).
