14 * This file implements a configuration backend for Windows registry. All the
15 * configuration information is stored in the registry and the format for
16 * network configuration fields is same as described in the sample
17 * configuration file, wpa_supplicant.conf.
19 * Configuration data is in
20 * \a HKEY_LOCAL_MACHINE\\SOFTWARE\\%wpa_supplicant\\configs
21 * key. Each configuration profile has its own key under this. In terms of text
22 * files, each profile would map to a separate text file with possibly multiple
23 * networks. Under each profile, there is a networks key that lists all
24 * networks as a subkey. Each network has set of values in the same way as
25 * network block in the configuration file. In addition, blobs subkey has
26 * possible blobs as values.
28 * Example network configuration block:
