## Discussion

Discussion Encode the return result to base64 and send it as the "license" key in response to an iOS license request. You can omit the signature argument if you include the signingKey argument in the ALDProvider initializer. Otherwise, pass in a signature of the license in the signature argument, signed by the signing certificate private key. For more information, see Licensing alternative distribution apps.
