title: Add encryption on uploading object in S3
body: <pre><code>import requests
  
  url = 'https://s3.amazonaws.com/&lt;some-bucket-name&gt;'
  
  data = { 'key': 'test/test.jpeg' }
  files = { 'file': open('test.jpeg', 'rb') }
  
  r = requests.post(url, data=data, files=files)
  </code></pre>
  <p>I want to upload an image to the S3 bucket as above.The S3 bucket is enabled with AES256 encryption. How will I be able to specify the encryption in post requests?</p>
