PHP/Amazon S3: Query string authentication

Question

I have been using the Zend_Service_Amazon_S3 library to access Amazon S3, but have been unable to find anything that correctly deals with generating the secure access URLs.

My issue is that I have multiple objects stored in my bucket with an ACL permission of access to owner only. I need to be able to create URLs that allow timed access. However, the documentation for Amazon S3 is very brief on the subject.

Could someone elaborate, or provide a link to something that explains how I might achieve this in PHP?

Answer 1

The documentation located in the authenticating REST requests section deals with generating the signature required for the URLs. It would be a simple case of implementing a PHP function that can generate this type of signature.
