Piracy Protection

EnTrail prohibits copying a registered (full version) product from one computer to another.  Key hardware can be changed on the installed computer without the requirement for the user to re-register the software.

Software Packages

The Administrator can be used to create Add-On "Packages" that can be digitally distributed or burried in your application as a resource.

Encryption, Security & Protection

The EnTrial SDK COM object/.NET assembly is obfuscated to prevent reverse engineering.  The EnTrail "Distribution File" that accompanies the software product is encrypted.  The EnTrial SDK will detect if the computer clock has been set back or if the software has be re-installed.
