b39d1280 14 * This file implements a configuration backend for Windows registry. All the
6fc6879b
JM		 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.
18 *
b39d1280
JM		 19 * Configuration data is in
20 * \a HKEY_LOCAL_MACHINE\\SOFTWARE\\%wpa_supplicant\\configs
6fc6879b
JM		 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.
27 *
b39d1280
JM		 28 * Example network configuration block:
29 * \verbatim
30HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs\test\networks\0000
31 ssid="example"
32 key_mgmt=WPA-PSK
