=head1 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);

=head1 DESCRIPTION
|
|
|
|
SSL_CTX_set_tmp_ecdh() sets ECDH parameters to be used to be B<ecdh>.
|

This macro is deprecated in favor of L<SSL_CTX_set1_groups(3)>.
|
|
|
|
SSL_set_tmp_ecdh() sets the parameters only for B<ssl>.
|
|
This macro is deprecated in favor of L<SSL_set1_groups(3)>.
|
|
|
