Does AWS CLI use SSL when uploading data into S3?

Question

Does the normal AWS CLI use SSL by default when transferring data into S3 with the following command?

Answer 1

By default, the AWS CLI uses SSL when communicating with AWS services.

AWS CLI command reference

Answer 2

I just tried running:

> aws s3 ls

and wireshark reports the response protocol used is TLSv1.2. So, yes it seems to be using SSL even for simple commands like ls.
