34 * @brief DBusKeyring data structure
36 * Types and functions related to DBusKeyring. DBusKeyring is intended
37 * to manage cookies used to authenticate clients to servers. This is
38 * essentially the "verify that client can read the user's homedir"
39 * authentication mechanism. Both client and server must have access
42 * The secret keys are not kept in locked memory, and are written to a
43 * file in the user's homedir. However they are transient (only used
44 * by a single server instance for a fixed period of time, then
45 * discarded). Also, the keys are not sent over the wire.
47 * @todo there's a memory leak on some codepath in here, I saw it once
48 * when running make check - probably some specific initial cookies
49 * present in the cookie file, then depending on what we do with them.
