Installing SSL Certificates via the CLI

Generate a CSR, upload a signed certificate, and verify HTTPS on your WTI device.

Step 1 — Access Web Access

From the CLI, issue /N and select option 23 for Web Access.

Step 2 — Open SSL Certificates

Select the SSL Certificates menu.

Step 3 — Fill Certificate Fields

Complete options 1–7 (8 optional). Ensure the Common Name exists in DNS.

Step 4 — Generate and Capture CSR

1. Select option 9 (CSR Commands), then option 1 to generate the CSR.
2. It will prompt you to create a password, define the password, and press Enter.

3. Select the option to Display CSR.
4. Configure your terminal application to receive the file:
   • Ensure the file is captured as a binary file.
   • For example, in Tera Term, check the Binary box.
   • Note: it takes approximately 2½ minutes to create the certificate.
5. Submit the certificate to a service that will generate a signed certificate.
   • Note: VeriSign or other services may take a couple of days to process the request.

Step 5 — Upload Signed Certificate

1. After receiving the signed certificate, navigate to CRT Commands and select the option to Upload Signed CRT Certificate.
2. Upload the server key in binary format.
   • In Tera Term: File → Send file (check Binary), then select Open.
   • Note: Because the file is small, there will be no transfer indicator. Import is nearly instantaneous. Press ESC to exit the upload menu.
3. View the uploaded CRT certificate to ensure it was applied.
   • From the CRT Commands menu, select Display Signed CRT Certificate.

Step 6 — Verify HTTPS

1. Open HTTPS to the device.
2. Click the lock icon and inspect the certificate.
