How to Reissue an SSL Certificate

Reissuing an SSL certificate is required when you need to update the certificate with a new private key or CSR (Certificate Signing Request). This process will revoke the old certificate, and you will need to reinstall the new one.

Steps to Reissue an SSL Certificate

1. Access the SSL Service Details

1. Log in to the Nubius Customer Portal.

2. Navigate to Services → My Services.

3. Locate your SSL Certificate service and click on it.

2. Request the Reissue

1. Click Reissue Certificate on the left-hand menu.

2. Enter a new CSR (Certificate Signing Request).

   • Ensure that the CSR is generated on the server where the certificate will be installed.

   • To generate a CSR on Linux, use the following command:

     openssl req -new -newkey rsa:2048 -nodes -keyout your.domain.key -out your.domain.csr

   • Follow the onscreen instructions
   • Keep the private key secure, as it will be required for SSL installation.

3. Remove any previous data in the CSR field and paste the new CSR.

4. Click Continue.

3. Complete the Validation Process

• The validation process is the same as when purchasing an SSL certificate.

• Choose one of the validation methods:

  • Email Validation – Requires approval from an admin email.

  • DNS Validation – Requires adding a TXT record.

  • HTTP File Validation – Requires uploading a verification file.

4. Retrieve and Install the New SSL Certificate

1. Once reissued, go to Services → My Services → SSL Service.

2. Click Retrieve Certificate.

3. Install the new certificate using the new private key generated with the CSR.

4. If your hosting is with Nubius, contact Support for installation assistance.

5. If hosting externally, manually install the new certificate on your server.

Important Notes

• Reissuing an SSL certificate revokes the old one. The previous certificate will no longer be valid.

• You must install the new certificate using the new private key.

• The validation process must be completed again before the certificate is issued.
