Amazon Web Service S3 (AWS S3)
Used to authenticate with AWS S3 buckets.
Authenticates a connection with an Amazon S3 bucket. When you add it to an HTTP connection, every request to S3 is automatically signed with your AWS credentials using AWS Signature Version 4, so Amazon accepts it as coming from your account. You only fill in your keys and the region the bucket lives in; the signing happens for you on each request.
