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.

Note: This example requires Chilkat v9.5.0.88 or later.

Ruby

require 'chilkat'

success = false

# 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()

# 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.put_SharedLibPath("aetpkss1.dll")

success = pkcs11.Initialize()
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    exit
end

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

# Open a session.
readWrite = true
success = pkcs11.OpenSession(slotID,readWrite)
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    exit
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.
userType = 1
pin = "0000"
success = pkcs11.Login(userType,pin)
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    success = pkcs11.CloseSession()
    exit
end

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

# Revert to an unauthenticated session by calling Logout.
success = pkcs11.Logout()
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    success = pkcs11.CloseSession()
    exit
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.CloseSession()
if (success == false)
    print pkcs11.lastErrorText() + "\n";
    exit
end

print "PKCS11 Login and Logout successfully demonstrated." + "\n";
