        "description": "Smartcard object Wrappers\n=========================\n\nThis module provide cryptography compatible proxy class for using \na crypto smartcard , (such as yubi key, or PKCS#11 token) to\nprocess the actually cryptographic workload.\n\nThese are normally considered to be 'secure' tokens and the private\nkey they are normally configured so the private key is not extractable\nfrom the token's hardware. As a result you need to request the token\nto do any cryptographic operation for which you would normally use the\nprivate key.\n\nIn this module you will find a new abstraction of cryptography's \n`RSAPrivateKey` class called `RSAPrivateToken` which instead using\none the normal cryptography provided backend uses an hardware token \ndirectly.\n\nCurrently this means the PKCS#11 API, as provided on Linux by the\nopensc-pkcs11 [1]_ package. TokenCrypt uses the PyKCS11 library\nto wrap the opensc PKCS#11 library and needs a environment variable\nset so the library can be found on debian that would be\n\n.. code:: shell\n\n    export PYKCS11LIB=/usr/lib/x86_64-linux-gnu/opensc-pkcs11.so\n\n\nA use case of this library would be to use a yubikey to provide Oauth\nidentity services to python applications which use the requests-Oauth2 \nlibrary.  This is quite common if you are accessing 3rd party APIs to\ncloud service systems.\n\nIn this case a `RSAPrivateToken` can be provided to the library in the place\nof the  usual `RSAPrivateKey`. \n\nMany library examples show providing an PEM encoded string, but they also\nwork with a subclass of cryptography's `RSAPrivateKey`, as shown below.\n\n\nExample\n-------\n\n.. code:: python\n\n    import TokenCrypt\n    from ThierAPI import APIConection, PrivateCredentials # Not a working example.\n\n    rsa_key = TokenCrypt.RSAPrivateToken(slot = 0 , key = 0, pin = '123456' )\n    with rsa_key:\n        credentials = PrivateCredentials(args.consumer_key, rsa_key)\n        api = APIConection(credentials)\n\n        do_something_with(api)\n\n\n\n.. [1] This is the package name in debian Stretch, Buster, Bullseye(so far), your\n      distribution may vary.\n\n\nCurrent Status\n--------------\n\nThis is an initial proof of concept release which is design to have enough\ncode to support working as an Oauth client. As a result the only action currently\nimplemented on the key is signing.\n\n\nBut there is a lot todo, Pull requests and bug reports welcome.\n\nTODO\n----\n\n    - Implement `RSAPublicToken` .\n    - Dynamically select the signing mechanism based to the provided \n      padding and hash.\n    - Implement decrypt.\n    - Implement certificate extraction.\n\n\n",
