# Starting API Manager with SSL

> Starting API Manager with SSL/TLS certificate

First, upload your certificate file with .p12 extension to Kubernetes as a secret.

```powershell theme={null}
kubectl create secret generic manager-tls --from-file=manager.p12 -n apinizer
```

Finding the Alias of a certificate:

```powershell theme={null}
keytool -list -v -keystore  manager.p12 -storetype PKCS12
```

Creating PKCS12 from JKS:

```powershell theme={null}
keytool -genkeypair -alias <ALIAS> -keyalg RSA -keysize 4096 -storetype PKCS12 -keystore manager.p12 -validity 3650 -storepass <PASSWORD>
```

<Info>
  Add your file with .p12 extension to the /etc/ssl/certs directory.
</Info>

Variables that should be in the deployment yaml definition:

| Variable                  | Description                                                                                                                 |
| ------------------------- | --------------------------------------------------------------------------------------------------------------------------- |
| SSL\_KEY\_STORE           | Path to the keystore containing the SSL certificate. In our example, we want Spring Boot to search for it in the classpath. |
| SSL\_KEY\_STORE\_PASSWORD | Password used to access the keystore.                                                                                       |
| SSL\_KEY\_STORE\_TYPE     | Type of keystore (Usage: PKCS12).                                                                                           |
| SSL\_KEY\_ALIAS           | Alias identifying the key in the keystore.                                                                                  |
| SSL\_ENABLED              | Enables the Spring Boot application to use HTTPS protocol.                                                                  |
| SERVER\_PORT              | Port the server listens on. 8443 should be used.                                                                            |

## Certificate Creation

Steps to create your own certificate:

```powershell theme={null}
# Create Private Key
openssl genrsa -out server.key 2048

# Create CSR (Certificate Signing Request)
openssl req -new -key server.key -out server.csr

# Signed Certificate
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

# PKCS#12 format
openssl pkcs12 -export -out manager.p12 -inkey server.key -in server.crt
```
