--- layout: default title: Storage --- ## 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' )
