NAME

       SSL_get_peer_tmp_key, SSL_get_server_tmp_key, SSL_get_tmp_key - get information about
       temporary keys used during a handshake

SYNOPSIS

        #include <openssl/ssl.h>

        long SSL_get_peer_tmp_key(SSL *ssl, EVP_PKEY **key);
        long SSL_get_server_tmp_key(SSL *ssl, EVP_PKEY **key);
        long SSL_get_tmp_key(SSL *ssl, EVP_PKEY **key);

DESCRIPTION

       SSL_get_peer_tmp_key() returns the temporary key provided by the peer and used during key
       exchange. For example, if ECDHE is in use, then this represents the peer's public ECDHE
       key. On success a pointer to the key is stored in *key. It is the caller's responsibility
       to free this key after use using EVP_PKEY_free(3).

       SSL_get_server_tmp_key() is a backwards compatibility alias for SSL_get_peer_tmp_key().
       Under that name it worked just on the client side of the connection, its behaviour on the
       server end is release-dependent.

       SSL_get_tmp_key() returns the equivalent information for the local end of the connection.

RETURN VALUES

       All these functions return 1 on success and 0 otherwise.

NOTES

       This function is implemented as a macro.
