+## 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'
+		)
