See more Code Signing Examples

Demonstrates how to Authenticode sign an EXE or DLL.

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

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# First create the following JSON to specify that SHA256 is to be used,
# and provide timestamp server information.
