How do I generate a CSR in cPanel?

A CSR (Certificate Signing Request) is the encoded text you provide when buying an SSL certificate. It contains your domain and organisation details and is created with a matching private key. This guide explains how to generate one in cPanel.

When you need a CSR #

You need a CSR when buying a paid or third-party SSL certificate. If you use Disoh’s free AutoSSL, you do not need a CSR, as certificates are issued automatically.

Generating the CSR #

1. Log in to cPanel.
2. In the Security section, open SSL/TLS.
3. Click Certificate Signing Requests (CSR).
4. Fill in your domain (common name), organisation, city, state, and country.
5. Click Generate.

Using the CSR #

• Copy the CSR text into your SSL provider’s order form.
• cPanel keeps the matching private key; do not delete it.
• Once the certificate is issued, install it in cPanel.

Filling in details correctly #

Enter the domain exactly as you want it secured. Provide accurate organisation details, as some certificate authorities validate them. For a simple domain-validated certificate, the domain is the key field.

Troubleshooting #

• Certificate rejected: confirm the common name matches your domain.
• Key missing at install: use the key cPanel generated with this CSR.
