SSL_get_server_tmp_key(3)           OpenSSL          SSL_get_server_tmp_key(3)



NAME
       SSL_get_server_tmp_key - get information about the server's temporary
       key used during a handshake

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/ssl.h>

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

DESCRIPTION
       SSL_get_server_tmp_key() returns the temporary key provided by the
       server and used during key exchange. For example, if ECDHE is in use,
       then this represents the server'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). This function may
       only be called by the client.

RETURN VALUES
       SSL_get_server_tmp_key() returns 1 on success or 0 otherwise.

NOTES
       This function is implemented as a macro.
