+
+### Connect with HCP Vault using SSL
+
+Before using SSL with Oracle RDS, you must configure a option group with SSL and set the following:
+
+- `SQLNET.SSL_VERSION` to `1.2`
+- `SQLNET.CIPHER_SUITE` to one of `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384`, `TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384`, `TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256`, `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256`, `TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA`, or `TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA`
+
+If the AWS RDS Oracle instance Vault is trying to connect to uses an SSL listener, the database
+plugin will require extra configuration using the `connection_url` parameter:
+
+```shell-session
+$ vault write database/config/oracle \
+  plugin_name=vault-plugin-database-oracle \
+  connection_url='{{username}}/{{password}}@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=<host>)(PORT=<port>))(CONNECT_DATA=(SERVICE_NAME=<service_name>))(SECURITY=(SSL_SERVER_CERT_DN="<cert_dn>")(MY_WALLET_DIRECTORY=<path_to_wallet>)))' \
+  allowed_roles="my-role" \
+  username="VAULT_SUPER_USER" \
+  password="myreallysecurepassword"
+```
+
+For example, the SSL server certificate distinguished name for AWS RDS and path to the Oracle Wallet
+to use for connection and verification could be configured using:
+
+- Wallet location and permissions are managed by the HCP platform. The wallet is available at `/etc/vault.d/plugin/oracle/ssl_wallet`.
+- The distinguished name for the current AWS RDS CA is in the format `SECURITY=(SSL_SERVER_CERT_DN="C=US,ST=Washington,L=Seattle,O=Amazon.com,OU=RDS,CN=your-rds-endpoint-url")`.
+- A listener on port `2484` is enabled by adding `SSL` to a RDS option group and applying the option group with SSL to your Oracle RDS instance.
+- Replace `your-rds-endpoint-url` with the endpoint for your RDS instance in the `HOST` and `DN` parameters.
+
+-> **Note:** For more information on using SSL/TLS with AWS RDS, review the [Using SSL/TLS to encrypt a connetion to a DB instance](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.SSL.html) AWS documentation.
