Remarks

When using query string authentication you create a query, specify an expiration time for the query, sign it with your signature, place the data in an HTTP request, and distribute the request to a user or embed the request in a web page.

A PreSigned URL can be generated for GET, PUT, DELETE and HEAD operations on your bucketName, keys, and versions.
