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.
