## Signing Code with Authenticode

This section demonstrates how to sign code by creating digital signatures and associating them with files using Authenticode, which is provided with the ActiveX SDK. Creating a fully verifiable certificate may assume the existence of a complex hierarchy of CAs. A root certificate and a root private key are provided for testing purposes only. If you are an independent software vendor, you must obtain a certificate from GTE, VeriSign, Inc., or another CA before you begin signing code.
