Pre-signed 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 and expiration date and time.

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

  • Anyone who receives the presigned URL can then access the object.
