PKCS11 Import an Existing RSA Public Key onto the HSM

See more PKCS11 Examples

Demonstrates how to import an existing RSA Public Key onto a smart card or token.

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

Perl

use chilkat();

$success = 0;

# 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.

# Establish a logged-on session.

# To store the public key on the token so that it persists after the PKCS11 session, set token = 1.
$attrs->UpdateBool("token",0);

# Provide the RSA public key material
$attrs->UpdateString("modulus",$xml->getChildContent("Modulus"));

# Returns the PKCS11 object handle of the created key.
