b39d1280 | 8 | * This file implements a configuration backend for Windows registry. All the |
6fc6879b JM |
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. | |
12 | * | |
b39d1280 JM |
13 | * Configuration data is in |
14 | * \a HKEY_LOCAL_MACHINE\\SOFTWARE\\%wpa_supplicant\\configs | |
6fc6879b JM |
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. | |
21 | * | |
b39d1280 JM |
22 | * Example network configuration block: |
23 | * \verbatim | |
24 | HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs\test\networks\0000 | |
25 | ssid="example" | |
26 | key_mgmt=WPA-PSK | |
