(PowerShell) 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.

$cert = New-Object Chilkat.Cert

# If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
$cert.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 -eq $false) {
    $($cert.LastErrorText)
    $("Certificate not loaded.")
    exit
}

# 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.
