high level PKCS#11 interface for Python

 A high level, "more Pythonic" interface to the PKCS#11 (Cryptoki) standard to
 support HSM and Smartcard devices in Python.
 .
 The interface is designed to follow the logical structure of a HSM, with
 useful defaults for obscurely documented parameters. Many APIs will optionally
 accept iterables and act as generators, allowing you to stream large data
 blocks for symmetric encryption.
 .
 It also includes numerous utility functions to convert between PKCS#11 data
 structures and common interchange formats including PKCS#1 and X.509.
 .
 The library is fully documented and has a full integration test suite for all
 features, with continuous integration against multiple HSM platforms including
 Entrust nShield, Opencryptoki TPM and OpenSC/Smartcard-HSM/Nitrokey HSM.
