Software Description
Software Compress is designed for pack and protect your EXE-files. What's New in This Release: [ read full changelog ]
Executable file always contains superfluous code. It allows compress exe-file up to 30-60% original. However, there is not enough to pack exe-file to archive. It must have an added loader-unpacker to run. Unpacked piece of code loads packed code to memory, to unpack and run it. We implemented this algorithm in our software.
Algorithm uses one-pass compression and dictionary and provides highest compression level. When packed program runs, it reads the dictionary and unpacks code into RAM in one pass. The unpacking speed is very fast (40 megabytes per second) because compression takes some time (few seconds). So no delays during execution of the packed program.
Crack and patch protection is provided by packing original code. Altering packed code will result to broken archive and impossible unpacking. Disassembly protection bases on it too. Cracker would obtain only source code of unpacker section and not original code.
Limitations:
%26#183; compresses up to 50% only
%26#183; FULL version now provides SCR and DLL compression
%26#183; LITE version: entrypoint changes
%26#183; Realtime unpacker fixes
