(Go) PKCS11 Generate Secret Key (such as AES)

See more PKCS11 Examples

Generates a symmetric secret key such as AES on the HSM.

Note: This example requires Chilkat v9.5.0.96 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.
