REXDESK: activate a licence and encrypt logs

Activate a REXDESK licence and create the keys that protect your data. Then encrypt a logger's files, or lock the logger so that only REXDESK with your key can read it or talk to it.

What needs a licence

REXDESK is free to download and use for configuring REXGEN loggers and exporting their data. Log encryption is a licensed feature, available on request. So is creating more than one snapshot file.

To ask for a licence, contact an engineer.

Activate a licence

You need administrator rights on the PC and an internet connection.

1. Open the licence window. In REXDESK, select Help > License.
2. Start the import. In the License window, select Import. The Activation window opens.
3. Enter the code. Select Type license identification code and paste the code Influx Technology sent you. Or select Browse license file from disk and select the licence file. Then select OK.

   

4. Check the status. Back in the License window, License status reads Active.

Encrypt logs and lock the device

1. Create a key. Generate or import a key in the Encryption Manager first.
2. Open the encryption settings. In Device Configuration, select Encrypt.
3. Choose the key. Select it in the Encryption Key list.
4. Choose the protection. Tick Encrypt Datalogs to encrypt the log files the logger writes. Tick Lock Device to stop anyone without the key communicating with the logger. You can tick both.

   

5. Send the configuration. Select Run. Logs recorded from now on are encrypted .rxe files.

Read encrypted logs

1. Select the key. In the Encryption Manager, select the key the logs were encrypted with and select Use Selected Key.
2. Download and export as usual. See REXDESK: download and export your logs.

To decrypt from the command line, pass the key file to convert-folder with the -E option. See REXDESK: convert, configure and reflash from the command line.
