Lua Requires Chilkat v9.5.0.88+

PKCS11 Login / Logout

See more PKCS11 Examples

Sample code showing how to login and logout of a PKCS11 session. A session becomes authenticated when Login is called, and returns to the unauthenticated state when Logout is called. A smart card's PIN is passed to the Login method. 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()

-- Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
-- or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
pkcs11.shared_lib_path = "aetpkss1.dll"

local success = pkcs11:initialize()
if not success then
    print(pkcs11.last_error_text)
    return
end

-- Pass -1 for the slotID to open a session on the first non-empty slot.
local slotID = -1

-- Open a session.
local readWrite = true
success = pkcs11:open_session(slotID, readWrite)
if not success then
    print(pkcs11.last_error_text)
    return
end

-- Make it an authenticated session by calling Login.
-- The smart card PIN is passed to the Login method.
-- The user type can be one of three choices:
-- 0 - Security Officer
-- 1 - Normal User
-- 2 - Context Specific.
-- You'll likely always login as the Normal User.
local userType = 1
local pin = "0000"
success = pkcs11:login(userType, pin)
if not success then
    print(pkcs11.last_error_text)
    success = pkcs11:close_session()
    return
end

-- Do what is needed with the authenticated session...
-- ...
-- ...

-- Revert to an unauthenticated session by calling Logout.
success = pkcs11:logout()
if not success then
    print(pkcs11.last_error_text)
    success = pkcs11:close_session()
    return
end

-- When finished, close the session.
-- It is important to close the session (memory leaks will occur if the session is not properly closed).
success = pkcs11:close_session()
if not success then
    print(pkcs11.last_error_text)
    return
end

print("PKCS11 Login and Logout successfully demonstrated.")
