+## AWS Specific Options
+
+Here's a couple Fog features specific only to AWS S3.
+
+**Encryption**. Amazon provides the option to AES256 encrypt files at rest on 
+upload by setting the "x-amz-server-side-encryption" HTTP request header to 
+AES256. You can short hand set this HTTP header via the ````encryption```` key 
+value pair. For example,
+
+    # encrypt file at rest
+    file = directory.files.create(
+      :key      => 'resume.html',
+      :body     => File.open("/path/to/my/resume.html"),
+      :public   => true, 
+      :encryption   => 'AES256'
+    )
