Self-sign Ensure this checkbox is selected, which indicates that you are creating a self-signed
certificate.
Validity in days This field appears after the Self-sign checkbox is selected.
Type the number of days for which the self-signed certificate will be valid.
A password is not required for a self-signed certificate so the Challenge and Confirm Challenge
fields disappear.
1) Click Create New TLS Key to create both the self-signed certificate and private key. This may take
several minutes to complete.
2) Once complete, do the following:
a. a. Double check the data shown in the New TLS Certificate section.
b. b. If correct, click "Install Key and Certificate" to install the self-signed certificate and private key.
Tip: To verify whether the certificate has been installed successfully, check the data shown in the
Active TLS Certificate section.
If incorrect, click "Delete Key and Certificate" to remove the self-signed certificate and
private key, and then repeat the above steps to re-create them.
3) (Optional) To download the self-signed certificate and/or private key, click Download Certificate or
Download Key in the New TLS Certificate section.
• • You are prompted to open or save the file. Click Save to save it onto your computer.
Note: The Download Key button in the Active TLS Certificate section is for downloading the private
key of the currently-installed certificate rather than the newly-created one.
Installing or Downloading Existing Certificate and Key
You can download the already-installed certificate and private key from any PRO4X for backup or file
transfer. For example, you can install the files onto a replacement PRO4X, add the certificate to your
browser and so on.
If valid certificate and private key files are already available, you can install them on the PRO4X without
going through the process of creating a CSR or a self‑signed certificate.
