# 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.
# (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
$pkcs11->SharedLibPath('C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll');

# Establish a logged-on session. (We can typically skip the login by passing an empty PIN if only working with public keys)
# Use your actual PIN here, or an empty string to skip login.

my $userType = 1;
my $success = $pkcs11->QuickSession($userType, $pin);

# Get the handle of the public key we wish to export.
# You can find public keys in many different ways.
# This example will search for a public key by label.

# Provide a template to find a PKCS11 object.

# Find the public key with the label "Belgium eHealth".
$jsonTemplate->UpdateString('class', 'public_key');
