-### Encryption
-
-`cottoncandy`provides a transparent encryption interface for AWS S3 and Google Drive. This requires the `pycrypto` package. 
-
-**WARNING**: Encryption is an advance feature. Make sure to create a backup of the encryption keys  (stored in `~/.config/cottoncandy/options.cfg`). If you lose your encryption keys you will not be able to recover your data!
-
-```python
->>> import cottoncandy as cc
->>> cci = cc.get_encrypted_interface('my_bucket_name',
-                                      ACCESS_KEY='FAKEACCESSKEYTEXT',
-                                      SECRET_KEY='FAKESECRETKEYTEXT',
-                                      endpoint_url='https://s3.amazonaws.com')
