Configuration Files Encryption
You can secure the exchange of configuration files between the server and the Mediatrix 4104. A privacy key
allows the unit to decrypt a previously encrypted configuration file.
To encrypt a configuration file (generic or specific), you must use the MxCryptFile application. MxCryptFile is
a command line tool that encrypts files before sending them to the Mediatrix 4104 unit. Contact your sales
representative for more details.
The following describes how to decrypt a previously encrypted generic or specific configuration file. You must
have one key for the generic configuration file and another key for the specific configuration file.

To decrypt a configuration file:
1. In the Encryption section of the Configuration File page , select Enable in the Configuration File
Encryption field.
Figure 20: Management – Encryption section
The Mediatrix 4104 will be able to decrypt the next encrypted generic or specific configuration file.
If you select
Disable , the configuration file is not decrypted by the unit and the configuration update
fails.
2. Set the proper decryption password field with the password used to decrypt the configuration file.
The password is encoded in hexadecimal notation. You can thus use characters in the range 0-9,
A-F. All other characters are not supported.
Each character encodes 4 bits of the key. For instance, a 32-bit key requires 8 characters.
• If you enter too many bits, the key is truncated to the first 448 bits.
• If you do not enter enough bits, the key is padded with zeros.
For instance, a 32-bit key could look like the following: A36CB299.
This key must match the key used for the encryption of the relevant configuration file.
If the field is empty, the configuration file is not decrypted.
3. Click Submit if you do not need to set other parameters.
