=head1 NAME
|
|
|
|
SSL_get_peer_tmp_key, SSL_get_server_tmp_key, SSL_get_tmp_key - get information
|
|
about temporary keys used during a handshake
|
|
|
|
=head1 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);
|
|
|
|
=head1 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
|
|
B<*key>. It is the caller's responsibility to free this key after use using
|
|
L<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.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
All these functions return 1 on success and 0 otherwise.
|
|
|
|
=head1 NOTES
|
|
|
|
This function is implemented as a macro.
