- QUOTE: Requests to AWS must be signed — that is, they must include information that AWS can use to authenticate the requestor. Requests are signed using the access key ID and secret access key of an account or of an IAM user. ...
  ... If you are using one of the AWS SDKs, the AWS Command Line interface (CLI), or a service-specific CLI, you do not need to worry about signing requests. All you need to do is configure the tools with one or more access keys. These tools construct and send requests to AWS for you, and as part of that process, they sign the requests using an access key that you provide.
