The Sheriff Software Development Kit (SDK) protects 32-bit & 64-bit Windows applications against illegal copying.

Sheriff offers the convenience of software-based protection - no need for dongles.

Sheriff offers unrivalled security, flexible licensing and ease of use via:

  • Windows DLL
  • ActiveX (OCX) control

Windows DLL is ideal for protecting programs written in Visual C++ while the ActiveX control works great with Visual Basic.

The Sheriff API enables you to completely customise every aspect of Sheriff - no fixed dialog boxes etc.

Sheriff also features Internet Software Registration (ISR), enabling you to distribute licence keys via the web.

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
