Encrypted configuration files can be downloaded from the provisioning server to
protect against unauthorized access and tampering of sensitive information (e.g., login
passwords, registration information). Yealink supplies a configuration encryption tool for
encrypting configuration files. The encryption tool encrypts plaintext
<y0000000000xx>.cfg and <MAC>.cfg files (one by one or in batch) using 16-character
symmetric keys (the same or different keys for configuration files) and generates
encrypted configuration files with the same file name as before.
For a Microsoft Windows platform, you can use a Yealink-supplied encryption tool
"Config_Encrypt_Tool.exe" to encrypt the <y0000000000xx>.cfg and <MAC>.cfg files
respectively.
Note
The way the IP phone processes the <MAC>.cfg file is the same to that of
the<y0000000000xx>.cfg file.
Procedure to Encrypt Configuration Files
To encrypt the <y0000000000xx>.cfg file:
1. Double click “Config_Encrypt_Tool.exe” to start the application tool.
The screenshot of the main page is shown as below:
When you start the application tool, a file folder named “Encrypted” is created
automatically in the directory where the application tool is located.
2. Click Browse to locate configuration file(s) (e.g., y000000000005.cfg) from your
local system in the Select File(s) field.
To select multiple configuration files, you can select the first file and then press and
hold the Ctrl key and select the next files.
Yealink also supplies a configuration encryption tool (yealinkencrypt) for Linux platform if
required. For more information, refer to
