PELock - is an application that allows you to protect Windows executable files (so called exe-protector). Besides that, PELock allows easy creation of application of evaluation-demo type, which use license key system.

 PELock features:

compression of the application (code, imports, resources), it's possible to decrease executable size even 70% of original file
encryption of code (publicly available cryptographic algorithms and algorithms build polymorphic ally)
reorganization of basic PE EXE structures in order to assure better ratio during compression
deletion of unnecessary structures in executable file (relocations, debug info)
protection against cracks and loaders
protection against debuggers (SoftICE, TRW, Turbo Debugger...)
protection against code tracing
counteraction to dumping application memory with the tools like ProcDump, LordPE...
application integrity check
many anty-debug and anty-trace tricks
advanced import table protection (so called "api redirection")
application password protection
simple in use license key system
application password protection
API system which allows communication between application and license key system
creation and verification of registration keys using public keys encryption algorithms (RSA)
ability to create trial keys and hardware dependent keys
keeping of the database and checkup of "stolen" (illegal) registration keys
ready to use samples of license key system in C/C++/Delphi
user-friendly interface
many option, which allow you the customize protection to your needs
entire thing written in assembler (win32asm)
