(Perl) PKCS11 Export Public Key from HSM

See more PKCS11 Examples

Demonstrates how to export a public key from a smartcard or token.

Note: This example requires Chilkat v9.5.0.96 or later.

Chilkat Perl Downloads Perl Module for Windows, MacOS, Linux, Alpine Linux, Solaris

use chilkat();

# 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 == 0) {
    print $pkcs11->lastErrorText() . "\r\n";
    exit;
}

# 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() . "\r\n";
    exit;
}

# Export to a Chilkat public key object.
$pubKey = chilkat::CkPublicKey->new();
$success = $pkcs11->ExportPublicKey($pubKeyHandle,$pubKey);
if ($success == 0) {
    print $pkcs11->lastErrorText() . "\r\n";
    exit;
}

# Get the public key as PKCS8 PEM.
print $pubKey->getPem(0) . "\r\n";
