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

Looking at the pastebin link Becky provided, I believe it translates to something like this in the new API:

from M2Crypto import Engine, m2

dynamic = Engine.load_dynamic_engine("pkcs11", "/Users/martin/prefix/lib/engines/engine_pkcs11.so")

pkcs11 = Engine.Engine("pkcs11")

pkcs11.ctrl_cmd_string("MODULE_PATH", "/Library/OpenSC/lib/opensc-pkcs11.so")

r = pkcs11.ctrl_cmd_string("PIN", sys.argv[1])

key = pkcs11.load_private_key("id_01")

So I am betting that if you substitute "/Users/martin/prefix/lib/engines/engine_pkcs11.so" with "/usr/local/ssl/lib/engines/engine_pkcs11.so" and "/Library/OpenSC/lib/opensc-pkcs11.so" with "/usr/lib/libeTPkcs11.so" you might get it to work with Aladdin.
