+(Optional) The redis password can be passed in encrypted using the `aes-256-cbc` encryption algorithm. To do so, pass in the following environment variables, in addition to the encrypted password:
+- `DECRYPT_REDIS_PASS=true`
+- `ENCRYPTION_KEY=<32 Byte hex string that was used for encryption>`
+- `ENCRYPTION_IV=<16 Byte hex string that was used for encryption>`
