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

I tried the code that Heikki suggested (minus one line) and got the same error as Erlo. For load_private_key(), how do I know what to put in for the argument?

dynamic = Engine.load_dynamic_engine("pkcs11", "/usr/local/ssl/lib/engines/engine_pkcs11.so")
#  m2.engine_free(dynamic) this line gave me an error TypeError: in method 'engine_free', argument 1 of type 'ENGINE *'

pkcs11 = Engine.Engine("pkcs11")
pkcs11.ctrl_cmd_string("MODULE_PATH", "/usr/lib/libeTPkcs11.so")

r = pkcs11.ctrl_cmd_string("PIN", "password")

key = pkcs11.load_private_key("id_01")
