This is a simple, secure and affordable licensing for .NET applications and components

Visual Protection System (VPS) is a powerful .NET solution for licensing components and software using simple and secure encrypted license keys.

VPS uses a public key encryption algorithm to generate encrypted license keys which are virtually impossible for a cracker to reverse engineer from your code. Each license key contains a unique client identifier and may also contain additional product information to allow issuing of license which unlock certain features in your application.

VPS provides a complete solution for component and control developers. Components and controls licensed using VPS generate runtime licenses which are incorporated automatically by Visual Studio into the clients application.

The runtime licenses are keyed to the design time license that generated them - but they can not be extracted and used as design time licenses, nor can a design time license be reverse engineered from the runtime license.

Here are some key features of "Visual Protection System":

• Strong Encryption - VPS uses a public key encryption algorithm to verify license keys which makes it virtually impossible for a cracker to reverse engineer license keys from your code.
• Unique Licence Keys - Each generated license key contains a unique serial number which guarantees licence key uniqueness and allows tracking of license keys.
• Feature Unlocking - Additional product information can be encrypted into license keys when they are generated allowing you to unlock specific software features.
• Component/Control Licensing - VPS provides a complete solution for component and control developers. Components and controls licensed using VPS generate runtime licenses which are incorporated automatically by Visual Studio into the clients application. Design time licenses cannot be reverse engineered from the runtime license.
• Time/Usage Limited Evaluations - VPS provides support for creating evaluation versions that are either time or usage (ie fixed number of uses) limited.
• Royalty Free - the Licensing System is licensed per developer. You can build as many applications as you want and distribute them without paying any further royalties.
