What's new in V1.8.5

• Added BackTimeTolerance property to TimeBomb and UsageBomb classes
• Changed the trial key verification mechanism

Ellipter is a powerful yet easy to use 100% managed .NET library for licensing applications using user friendly and secure license keys based on asymmetric elliptic curves encryption. It uses an asymmetric elliptic curves encryption algorithm to create and verify license keys which makes it impossible for anyone to create any keygens by reverse-engineering your code or even having full access to it.

Product keys generated by Ellipter are as short as possible: 29 characters length when no product info is embedded. Each generated license key contains an ID which guarantees license key uniqueness and allows secure identification of license keys. Based on the ID any license key can be blacklisted, which means it won't be accepted by Ellipter even if it is valid. Additional product information can be embedded into license keys when they are generated which can then be used for enabling specific software features.

Ellipter works with Windows Forms and WPF applications, ASP.NET applications, web services, Windows services, components and class libraries and supports all .NET 1.0 - 4.5 versions.

Features:

• User Interface - Ellipter has a full featured User Interface with a Public/Private keys pair Generator, Serials Generator, Serials Validator and Checksum Calculator.
• Royalty Free - Ellipter is licensed per developer. You can build as many applications as you want and distribute them without paying any further royalties.
• Easy to Use - Ellipter's most important feature is it's simplicity of use. Most of the time all you need to write is just 3 lines of code.
• Examples and Documentation - Ellipter comes with C# and Visual Basic examples of its major features, and with full offline and online documentation.
• Hardware ID reading - With Ellipter you can read hardware IDs for computer components or a combination of components for machine identification and computer specific registration keys creation with MachineInfoReader.
• Checksum Calculator - Use ChecksumCalculator to easily calculate CRC checksums for any string and embed it into a product key.
