Upload a certificate

To use SSL certificates, you must either have an existing SSL certificate or use a free SSL certificate provided by Let's Encrypt. GreenNode stores certificates securely; the storage system is encrypted, and certificates are inaccessible to anyone, including GreenNode employees.

The Certificate Manager supports uploading and managing two types of certificates:

• TLS/SSL Certificates

• CA Certificates

1. Uploading TLS/SSL Certificates

1. Access the Certificate Manager: Go to https://hcm-3.console.vngcloud.vn/vserver/load-balancer/certificate.

2. Click "Upload Certificate": A pop-up window will appear for you to enter certificate information.

3. Fill in Certificate Details:

   • Friendly Name: We recommend using the domain name as the friendly name.

     • Certificate Content: Paste your server certificate domain (usually with the *.crt extension) in PEM format.

     • Certificate Chain: Paste the certificate chain, including the server certificate and any intermediate certificates (if applicable), in PEM format.

         ---BEGIN CERTIFICATE--- [Intermediate#1 certificate] (optional) ---END CERTIFICATE---
         ---BEGIN CERTIFICATE--- [Intermediate#2 certificate] (optional) ---END CERTIFICATE---
