Presigned URLs

• All objects by default are private.

  • Only the object owner has permission to access these objects.

• However, the object owner can optionally share objects with others by creating a presigned URL, using their own security credentials, to grant time-limited permission to download the objects.

• When you create a presigned URL for your object, you must provide:

  • Your security credentials, specify a bucket name, an object key, specify the HTTP method (GET to download the object) and expiration date and time.

• The presigned URLs are valid only for the specified duration.
