SSL_get_peer_tmp_key3ssl
Get information about temporary keys used during a handshake
Usage
#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);
Overview
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.

This function is implemented as a macro.
