The Sheriff Software Development Kit (SDK) protects 32-bit Windows applications against illegal copying. Sheriff provides software-based protection - no need for key disks or dongles. Sheriff offers unrivalled security, flexible licensing and ease of use. Sheriff can be implemented via Windows DLL, Static Library or ActiveX (OCX) control. Windows DLL or Static Library are ideal for protecting programs written in Visual C++, while the ActiveX control works great with Visual Basic, Visual FoxPro and Delphi. The Sheriff API enables you to completely customise every aspect of Sheriff - no fixed dialog boxes etc. Sheriff is competitively priced - a single, royalty-free payment for each product you need to protect. You can evaluate Sheriff for as long as you like by downloading the full SDK.
