Lua Requires Chilkat v9.5.0.96+

PKCS11 Find all Private Keys

See more PKCS11 Examples

Demonstrates how to list all private keys on an HSM. Lua

local chilkat = 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.

local pkcs11 = chilkat.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.shared_lib_path = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll"

-- Establish a logged-on session.
-- Use your actual PIN here.
local pin = "0000"
local userType = 1
local success = pkcs11:quick_session(userType, pin)
if not success then
    print(pkcs11.last_error_text)
    return
end

-- Note: A logged-on session is required to list private keys.

local json = chilkat.JsonObject.new()
json.emit_compact = false

success = pkcs11:find_all_keys("private", json)
if not success then
    print(pkcs11.last_error_text)
    return
end

print(json:emit())
