(Chilkat2-Python) ScMinidriver - Import Private Key to Smart Card

See more ScMinidriver Examples

Demonstrates how to import a private key to the "signature" or "key exchange" location in the Nth key container on a smart card.

# This example requires the Chilkat API to have been previously unlocked.

# Chilkat recommends the following free tool for interactively examining the contents of your smart card
# through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

# Let's first look at our smart card before importing a private key.
# Here's the view of our Gemalto (Thales) IDPrime MD T=0 smart card in the MGTEK tool:



# First let's load a private key into the Chilkat private key object.
# (Chilkat provides the ability to load private keys from many different sources and formats.
# this example loads from a PEM file.)
privKey = chilkat2.PrivateKey()
success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
if (success == False):
    print(privKey.LastErrorText)
    sys.exit()

scmd = chilkat2.ScMinidriver()

# First we need to acquire a context to the smart card in the reader where it is inserted.
# Reader names (smart card readers or USB tokens) can be discovered
# via List Readers or Find Smart Cards
readerName = "Alcor Micro USB Smart Card Reader 0"
success = scmd.AcquireContext(readerName)
if (success == False):
    print(scmd.LastErrorText)
    sys.exit()

# If successful, the name of the currently inserted smart card is available:
print("Card name: " + scmd.CardName)

# To import a private key, we'll need to be PIN authenticated.
# For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
pinId = "user"
retval = scmd.PinAuthenticate(pinId,"0000")
if (retval != 0):
    print("PIN Authentication failed.")
    scmd.DeleteContext()
    sys.exit()

# Let's import into the "key exchange" position in key container #7.
success = scmd.ImportKey(7,"kex",privKey,"user")
if (success == False):
    print("PIN Authentication failed.")
    scmd.DeleteContext()
    sys.exit()

scmd.DeleteContext()

print("Success.")
