Description: PELock is a software security solution designed for protection of any 32 bit Windows applications against cracking, tampering and reverse engineering analysis.

PELock comes with a built-in licensing system, you can use it to easily add license key system for your application. You can also set various time-trial limitations for the protected application, e.g. 30 days trial.

You can closely integrate the protection and licensing features using dedicated SDK with hundreds of examples for C/C++, Delphi, Lazarus, Freepascal, PureBasic, PowerBASIC, D, Assembler with full source codes.

You can protect any compiled application file for Windows as long as it's compatible with Portable Executable format, no matter what programming language or development environment was used to create it.

PELock has a built-in binder for additional application DLL libraries, it's possible to merge your main application EXE file with any number of extra DLL libraries into single output EXE file.

PELock has been tested for all available 32 and 64 bit versions of the Windows operating system. And it's compatible with ALL of them.
