| Other programs communicate with cryptohomed using its DBUS API. This API | |
| exposes both synchronous and asychronous methods for mounting, unmounting, | |
| removing, and changing passwords. It also gives status information about the | |
| TPM. See cryptohome.xml for a brief listing of the APIs available. Note that | |
| the asyncrhonous APIs complete using a signal (AsyncCallStatus). The completion | |
| signals are guaranteed to be in-order. |
