Subject: Don't send a for ServerKeyExchange for kDHr and kDHd
X-Git-Tag: OpenSSL_1_1_0-pre1~1479
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=93f1c13619c5b41f2dcfdbf6ae666f867922a87a;p=oweals%2Fopenssl.git

Don't send a for ServerKeyExchange for kDHr and kDHd

The certificate already contains the DH parameters in that case.
ssl3_send_server_key_exchange() would fail in that case anyway.
