If you use RSA encryption in file exchange communication with Interactive Brokers, best practice requires that this key be backed up for security and retrieval purposes. Creating a backup is quick and ensures the longevity of your Key Pair.

Note: this tutorial assumes you have already set up a Key pair. If you need guidance to set up the Key pair please refer to this article, which is a prerequisite to the instructions below.

Please select one of the below links, according to your Operating System:

• Windows
• macOS

Windows

1. On the machine where the encryption keys are stored, create a new folder (e.g., on the Desktop).

2. Launch the application GPA Key Manager and select the encryption key you want to transfer. Please make sure that you see the text 'The key has both a private and a public part', in the details panel on the bottom of the window, as highlighted in the screenshot below.

3. Select the menu Keys and then click on Backup. Do NOT use Export, as this will only export the public part while you need both the public and the private key.

4. Save the key with a filename (e.g. secret-key-KEYID.asc) into the new Folder on the Desktop. A backup copy of the key pair will be created in the folder you selected.

macOS

1. On the machine where the encryption keys are stored, create a new folder (e.g., on your Desktop).
