Parameter
static.auto_provision.aes_key.mac <y0000000000xx>.cfg
Description
It configures the plaintext AES key for encrypting/decrypting the MAC-Oriented files (<MAC>.cfg,
<MAC>-local.cfg and <MAC>-contact.xml).
The valid characters contain: 0 ~ 9, A ~ Z, a ~ z and the following special characters are also sup-
ported: # $ % * + , - . : = ? @ [ ] ^ _ { } ~.
Example:
static.auto_provision.aes_key.mac = 0123456789abmins
Note: For decrypting, it works only if “static.auto_provision.aes_key_in_file” is set to 0. If the down-
loaded MAC-Oriented file is encrypted and the parameter “static.auto_provision.aes_key.mac” is left
blank, the phone will try to encrypt/decrypt the MAC-Oriented file using the AES key configured by the
parameter “static.auto_provision.aes_key.com”.
