5 * This software may be distributed under the terms of the BSD license.
6 * See README for more details.
8 * This file implements a configuration backend for Windows registry. All the
9 * configuration information is stored in the registry and the format for
10 * network configuration fields is same as described in the sample
11 * configuration file, wpa_supplicant.conf.
13 * Configuration data is in
14 * \a HKEY_LOCAL_MACHINE\\SOFTWARE\\%wpa_supplicant\\configs
15 * key. Each configuration profile has its own key under this. In terms of text
16 * files, each profile would map to a separate text file with possibly multiple
17 * networks. Under each profile, there is a networks key that lists all
18 * networks as a subkey. Each network has set of values in the same way as
19 * network block in the configuration file. In addition, blobs subkey has
20 * possible blobs as values.
22 * Example network configuration block:
