Details of Configuration Parameters:
auto_provision.aes_key_in_file
Description:
Enables or disables the Skype for Business phone to decrypt configuration files using the
encrypted AES keys.
0-Disabled

If it is set to 1 (Enabled), the Skype for Business phone will download
<y0000000000xx_Security>.enc and <MAC_Security>.enc files during auto provisioning,
and then decrypts these files into the plaintext keys (e.g., key2, key3) respectively using the
phone built-in key (e.g., key1). The Skype for Business phone then decrypts the encrypted
configuration files using corresponding key (e.g., key2, key3).
If it is set to 0 (Disabled), the Skype for Business phone will decrypt the encrypted
configuration files using plaintext AES keys configured on the Skype for Business phone.
