Need help using M2Crypto.Engine to access USB Token

Question

I am using M2Crypto-0.20.2. I want to use engine_pkcs11 from the OpenSC project and the Aladdin PKI client for token based authentication making xmlrpc calls over ssl.

Answer 1

That is exactly the code I've tried. But It ended with the following error:

Traceback (most recent call last):
  File "prog9.py", line 13, in 
    key = pkcs11.load_private_key("id_45")
  File "/usr/lib/pymodules/python2.5/M2Crypto/Engine.py", line 70, in load_private_key
    return self._engine_load_key(m2.engine_load_private_key, name, pin)
  File "/usr/lib/pymodules/python2.5/M2Crypto/Engine.py", line 60, in _engine_load_key
    raise EngineError(Err.get_error())
M2Crypto.Engine.EngineError: 11814:error:26096075:engine outines:ENGINE_load_private_key:not initialised:eng_pkey.c:112:

I'm using OpenSC PKCS11 lib, not aladdin lib. But I don't think the problem is closed.
