SSL_CTX_set_tmp_ecdh(3)             OpenSSL            SSL_CTX_set_tmp_ecdh(3)




NAME

       SSL_CTX_set_tmp_ecdh, SSL_set_tmp_ecdh, SSL_CTX_set_ecdh_auto,
       SSL_set_ecdh_auto - handle ECDH keys for ephemeral key exchange


SYNOPSIS

        #include <openssl/ssl.h>

        long SSL_CTX_set_tmp_ecdh(SSL_CTX *ctx, const EC_KEY *ecdh);
        long SSL_set_tmp_ecdh(SSL *ssl, const EC_KEY *ecdh);

        long SSL_CTX_set_ecdh_auto(SSL_CTX *ctx, int state);
        long SSL_set_ecdh_auto(SSL *ssl, int state);


DESCRIPTION

       SSL_CTX_set_tmp_ecdh() sets ECDH parameters to be used to be ecdh.  The
       key is inherited by all ssl objects created from ctx.  This macro is
       deprecated in favor of SSL_CTX_set1_groups(3).

       SSL_set_tmp_ecdh() sets the parameters only for ssl.  This macro is
       deprecated in favor of SSL_set1_groups(3).

       SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() are deprecated and have
       no effect.


RETURN VALUES

       SSL_CTX_set_tmp_ecdh() and SSL_set_tmp_ecdh() return 1 on success and 0
       on failure.
