I've set up an AWS S3 bucket, and it's working for transfers using the web UI, but I want to be able to use the "aws s3 sync" command. The only way I know how to use that command requires that I have an aws_secret_access_key associated with the bucket. However, I have utterly failed to discover out how to create this key, or how to supply a key for use with this bucket.
Can someone tell me how to do this, or point me at the right piece of documentation, please?
