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.
