Authenticode Sign using Smartcard or USB Token

See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL using a smartcard or USB token, such as a Yubikey.

Note: Chilkat's code signing class was added in v9.5.0.97

    -- There are many possible ways to load a Chilkat certificate object with a cert (and associated private key)
    -- from a variety of sources.  The only coding difference for any signing function in Chilkat,
