-The functions SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() can be used to
-make a server always choose the most appropriate curve for a client. If set
-it will override any temporary ECDH parameters set by a server. Previous
-versions of OpenSSL could effectively only use a single ECDH curve set
-using a function such as SSL_CTX_set_ecdh_tmp(). Newer applications should
-just call:
-
- SSL_CTX_set_ecdh_auto(ctx, 1);
-
-and they will automatically support ECDH using the most appropriate shared
-curve.
