# 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.

pkcs11 = Chilkat::CkPkcs11.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.put_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.
pin = "0000"
userType = 1
success = pkcs11.QuickSession(userType,pin)
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    exit
end

# 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.
jsonTemplate = Chilkat::CkJsonObject.new()

# Find the public key with the label "Belgium eHealth".
jsonTemplate.UpdateString("class","public_key")
jsonTemplate.UpdateString("label","Belgium eHealth")

pubKeyHandle = pkcs11.FindObject(jsonTemplate)
if (pubKeyHandle == 0)
    print pkcs11.lastErrorText() + "\n";
    exit
end

# Export to a Chilkat public key object.
pubKey = Chilkat::CkPublicKey.new()
success = pkcs11.ExportPublicKey(pubKeyHandle,pubKey)
if (success == false)
    print pkcs11.lastErrorText() + "\n";

# Get the public key as PKCS8 PEM.
