(Ruby) ScMinidriver - Import a Certificate to IDPrime MD T=0 Smart Card

See more ScMinidriver Examples

Demonstrates how to import a certificate and its private key to a key container on an ID Prime MD T=0 smartcard.

Note: Requires Chilkat v9.5.0.88 or later. This example only runs on Windows because ScMinidriver is a Windows-only class.

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

scmd = Chilkat::CkScMinidriver.new()

# Reader names (smart card readers or USB tokens) can be discovered
# via List Readers or Find Smart Cards
readerName = "SCM Microsystems Inc. SCR33x USB Smart Card Reader 0"

if (success == false)
    print scmd.lastErrorText() + "\n";

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

# The IDPRime MD smart card has 4 different PIN roles:
# "user" -- Primary Card PIN
# "admin" -- Administrator PIN
# "3" -- Digital Signature PIN
# "4" -- Unblock only PIN (PUK)
# To import a certificate to the "IDPrime MD T=0" smart card, we must first PIN authenticate using "user", and then also PIN authenticate using "3" (the Digital Signature PIN)
pinId = "user"
# (Of course, use your PIN which may be different than "0000")
retval = scmd.PinAuthenticate(pinId,"0000")
if (retval != 0)
    print "PIN Authentication failed." + "\n";
    scmd.DeleteContext()

# Load the cert + private key from a .p12/.pfx
# We got this .p12 from https://badssl.com/download/

# Note the last argument (the pin ID) is "3".  This is the required PIN ID for the IDPrime MD T=0 smart card.
