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.

# 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.
