Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. Ruby

require 'chilkat'

success = false

cert = Chilkat::CkCert.new()

# If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
cert.put_SmartCardPin("12345678")

# To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
# When testing in this way, it's best to have only a single smartcard or token connected to the system.
success = cert.LoadFromSmartcard("")
if (success == false)
    print cert.lastErrorText() + "\n";
    print "Certificate not loaded." + "\n";
    exit
end

# The LastErrorText property on all Chilkat objects will contain 
# information even when the method call is successful.
# You can examine the LastErrorText to see what Chilkat found and
# what decisions were made.
# 
# For example, if a certificate was successfully loaded via LoadFromSmartcard,
# but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
# then we would want to examine the LastErrorText from the call to
# LoadFromSmartcard to get detailed information about the card.
print cert.lastErrorText() + "\n";

print "Found: " + cert.subjectDN() + " serial=" + cert.serialNumber() + "\n";
