Why Crypkey?

Trusted Products Since 1992

For over 20 years now, CrypKey has been providing software developers with software licensing tools and software copy protection for Windows applications. Over that time, our easy to implement SDK and our quick and easy Instant product have evolved into a comprehensive set of tools that can accommodate almost any business sales model. Over the years we have added complementary products to our offering to assist you in selling your software how you want to.

When you purchase CrypKey you own the software. No Royalty Fees and modest pricing. Purchase CrypKey for each of your products and enjoy unlimited licensing. Each purchase even includes one free year of software maintenance.
