# Load Balancer SSL Setup
E2E Load Balancers support HTTPS traffic by handling SSL/TLS encryption at the Load Balancer level.  
This allows secure communication between users and your applications.

To configure HTTPS, customers must provide an SSL certificate, its corresponding **private key**, and the **certificate chain**.  
These components allow the Load Balancer to establish a secure connection, validate the certificate, and serve encrypted traffic to end users.

SSL configuration on the Load Balancer ensures:

- Secure access to applications over HTTPS  
- Centralized certificate management instead of installing SSL on every backend server  
- Better performance and easier scaling  
- Consistent security policies across all incoming traffic  


## Purchased SSL Certificates on E2E
When an SSL certificate is purchased from E2E, the customer receives:

- The signed SSL certificate  
- The intermediate/CA bundle  

The **private key is not included**, because:

- It is generated locally during CSR creation  
- E2E does not store or handle private keys  
- Load Balancers need the private key to process HTTPS traffic  

Because of this, purchased SSL certificates **cannot be directly used** with Load Balancers and must be manually imported.


## When SSL Must Be Imported Manually

You must import an SSL certificate manually in the following situations:

- You want to enable HTTPS (port 443) on a Load Balancer  
- You purchased an SSL certificate from E2E (private key is not included)  
- You generated the CSR and private key locally and only you have the key  
- You need the certificate to appear in the Load Balancer’s SSL selection dropdown  

The Load Balancer can only use SSL certificates that are imported with all required components:

- SSL Certificate  
- Private Key  
- Certificate Chain  


# Importing an SSL Certificate

## Step 1: Prepare SSL Files
Required files:

- Certificate (`.crt` / `.pem`)  
- Private key (`.key`)  
- Certificate chain (`.crt` / `.pem`)  


## Step 2: Import SSL Certificate in MyAccount
1. Open **MyAccount**  
2. Navigate to **Services → Certificate Manager**  
3. Click **Import SSL Certificate**  
4. Upload:
   - Certificate  
   - Private Key  
   - Certificate Chain  

After import, the certificate becomes available for Load Balancer selection.


## Step 3: Attach SSL to a Load Balancer
1. Go to **Compute → Load Balancer**  
2. Select your Load Balancer  
3. Add or edit a **HTTPS (443) listener**  
4. Choose the imported SSL certificate  
5. Save changes  

The Load Balancer will now handle HTTPS traffic using the imported SSL certificate.


## Important Notes
- SSL certificates purchased from E2E must be imported manually because the private key is not included.  
- Only imported certificates appear in the Load Balancer SSL dropdown.
