# 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 = Chilkat::CkPrivateKey.new()
success = privKey.LoadPemFile("qa_data/rsa/rsaPrivKey_pkcs8.pem")
if (success == false)
    print privKey.lastErrorText() + "\n";
    exit
end

scmd = Chilkat::CkScMinidriver.new()

# 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() + "\n";
    exit
end

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

# 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." + "\n";
    scmd.DeleteContext()
    exit
end

# 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." + "\n";
    scmd.DeleteContext()
    exit
end

scmd.DeleteContext()

print "Success." + "\n";
