Subject: Don't send a for ServerKeyExchange for kDHr and kDHd
X-Git-Tag: OpenSSL_1_0_2b~156
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fe82be2b33714949e24f107af94b5b75206a28cd;p=openssl

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.
