The pycrypto library is unmaintained, and keystonemiddleware currently
uses pycrypto to encrypt and decrpyt things before caching them.
This patch set removes the pycrypto dependency and updates the code
to use the cryptography library. See [1]. Replacing the cryptographic
library is backward compatible. See [2].
