17 SSL_get_peer_tmp_key() returns the temporary key provided by the peer
18 and used during key exchange. For example, if ECDHE is in use, then
19 this represents the peer's public ECDHE key. On success a pointer to
20 the key is stored in *key. It is the caller's responsibility to free
21 this key after use using EVP_PKEY_free(3).
22
23 SSL_get_server_tmp_key() is a backwards compatibility alias for
24 SSL_get_peer_tmp_key(). Under that name it worked just on the client
25 side of the connection, its behaviour on the server end is release-
26 dependent.
27
28 SSL_get_tmp_key() returns the equivalent information for the local end
29 of the connection.

32 All these functions return 1 on success and 0 otherwise.

35 This function is implemented as a macro.
