The comprehensive software copy protection and licensing solution.

CrypKey SDK (software developer kit) is a proven encryption tool that protects your software against illegal copying and unauthorized use. It’s a software-based solution, which means customers who use your CrypKey-protected application do not require a hardware key (i.e., a dongle). CrypKey SDK offers developers advanced functionality, customization, and control.

The developer’s choice for software protection and licensing.

CrypKey SDK offers maximum flexibility for implementing customized copy protection and licensing strategies. With CrypKey SDK, you embed the function calls into the source code of your application.
