   - **secretName** (required) - name of the data source secret (e.g. `watson`)
   - **encoding** (required) - option to encode the signature once it is generated: `hex`, `base64`, `base64url`, `base64percent`
       - `base64url` produces the same result as `base64` but in addition also replaces `+` with `-` , `/` with `_` , and removes the trailing padding character `=`
