PKCS11 Initialize Normal User PIN

See more PKCS11 Examples

Initializes the Normal User PIN from the Security Officer's logged-on session. This provides a way to reset the user PIN if it has been forgotten.

Note: Requires Chilkat v9.5.0.89 or greater.

Go

    // 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.

    // See PKCS11 Find Driver Library Path for information about how to find the 
    // PKCS11 driver file (if not explicitly known) for the plugged-in token or smart card in reader.
