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

# Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

my $pkcs11 = Chilkat2::Pkcs11->new;

# Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
# For example:
$pkcs11->SharedLibPath('C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll');

# Use your HSM's PIN.
my $pin = '0000';

# Normal user = 1
my $userType = 1;

# Establish a logged-on user session with the HSM.
my $success = $pkcs11->QuickSession($userType, $pin);
if (!$success) {
    print $pkcs11->LastErrorText, "\n";
    exit;
}

# Provide a template to find a PKCS11 object.
my $jsonTemplate = Chilkat2::JsonObject->new;

# Find an RSA private key with the label "MySshKey".
# Here's an example of how the key was originally imported:
# PKCS11 Import SSH Key
$jsonTemplate->UpdateString('class', 'private_key');
$jsonTemplate->UpdateString('key_type', 'rsa');
$jsonTemplate->UpdateString('label', 'MySshKey');

my $privKeyHandle = $pkcs11->FindObject($jsonTemplate);
if ($privKeyHandle == 0) {
    print $pkcs11->LastErrorText, "\n";
    exit;
}

# The private key handle is only valid during the PKCS11 session.
# If you wish to use the private key in another PKCS11 session,
# you'll first need to find it.  See:
print 'private key handle: ', $privKeyHandle, "\n";

# Do whatever you wish with the private key handle...
# ...
