(Ruby) PKCS11 Find all Public Keys

See more PKCS11 Examples

Demonstrates how to list all public keys on an HSM.

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

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require '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 needing to list 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";

end

# Note: To find public keys, we need a session, but it doesn't necessarily need to be logged-on.
