title: S3 - give each user access/secret keys for a user data directory
body: <p>Is it possible to dynamically create an access/secret keys for each user in my system that will allow them to read/write/list contents on a bucket with a specific prefix.</p>
  
  <p>for example: my bucket is userDataBucket.
  a user with id 77 is logged in. I would like to send him to the client access/secret so he can work with this directory:</p>
  
  <pre><code>s3://userDataBucket/users/77/
  </code></pre>
  
  <p>he must work only with this directory and not have access to any other directory.</p>
  
  <p>is such a thing possible?</p>
