バイナリで S3 キーを暗号化することは良い考えですか? どのように?
ありがとう!
I would recommend you do not include them in your app. Put them on a server with a REST based interface and limit the possibilities of the single user on the server side.
When the user gets you S3 credentials they will be able to abuse them! And they will always be able to get them when you include them in your app.
