<gs_provision version="1">

The mac element is not mandatory. It is designed this way because not all provision systems support 
MAC address. If it is present, the provision program will validate the mac element with the actual MAC 
address on the device. 
 

 

 

The XML configuration file may be encrypted using AES-256-CBC algorithm. The encryption password is 
defined in P1359 (XML Config File Password) of the configuration file. The encryption may use salt to 
enhance security. The algorithm to derive the key and IV from a password is the same as the one used 
by OpenSSL: 
 
The OpenSSL command-line to encrypt the file is as follows: 
Openssl enc –e –aes-256-cbc –k password –in config.xml –out cfgxxxxxxxxxxxx.xml 
 
Alternatively, users can also set the XML Config File Password in the web UI of the phone.  
 
 

 

 

When the XML configuration file is encrypted using this method, the phone would only be able to decrypt 
and parse the file if user set the XML Config File Password in P1349 of binary configuration file or in the 
web UI.
