Demonstrates how to Authenticode sign an EXE or DLL using a SafeNet USB token from Sectigo.

Requires Chilkat v10.0.0 or greater.

// Note: If the above fails, then use the SafeNet Authentication Client Tools
// to login to your token using your token password.
// You don't want too many failed logins, otherwise you'll lock the token.
