Secure Transmission of Sensitive Information

When working with various Armor teams, it may be required in the normal course of business to transfer sensitive data to us. In order to do this securely, we provide a public GPG key that you can use to encrypt such sensitive data prior to sending it to us – this guarantees that only Armor is able to read the data if it is intercepted in transit.

Prerequisites

Download and install GnuPG

Download and install Armor’s public GPG key

Download the key from the URL below, then run the following commands to install and trust the key:

https://www.armor.com/.well-known/support@armor.com.asc

Import the key to your key ring

Trust the key

This will open the key editor prompt gpg>. In that prompt type trust then enter 4 to fully trust this key. Press enter, then type quit and press enter again to exit.

Encrypt the sensitive file

Use the following command to encrypt a file – replace the path with your own target file.

This will create a file at /path/to/sensitive/file.txt.gpg with the encrypted data that only Armor Support can read. You can attach this file to your support request or via chat with an Armor agent.

As always, the file should be encrypted in transit (for example via TLS/HTTPS) even though the file is already encrypted at rest.

You should remove the sensitive file if it is no longer needed.
