decrypting before provisioning.
Procedure to Encrypt Configuration Files
To encrypt the <y0000000000xx>.cfg file:
1. Place the ―EncryptUtilityWindows.exe‖ tool and <y0000000000xx>.cfg file to the
same directory (i.e., D:\).
2. Open a command line window application (i.e., DOS window).
3. Enter the following command, and then press the <Enter> key.
D:EncryptUtilityWindows.exe 123456789abcdef0 e F:\y000000000038.cfg
D:\y000000000038.cfg
#D:EncryptUtilityWindows.exe <a 16-character secret key> e <a new
directory and file name of the encrypted configuration file> <the
directory and file name of the original configuration file>
4. Place the encrypted configuration file to the root directory of the provisioning
server.
The way for encrypting the <MAC>.cfg file is the same as the <y0000000000xx>.cfg file.
After encrypting the configuration files, you need to configure the AES keys on the IP
phone.
Procedure
AES keys can be configured using the configuration files or locally.
Configuration File
<y0000000000xx>.cfg
Configure the AES keys.
