Новая версия утилиты для сжатия файлов EXE, DLL, SCR, OCX и т.п с сохранением их полной работоспособности. Используется оригинальный алгоритм сжатия JCALG1, позволяющий значительно уменьшать размер исполняемого файла. Допускается оставлять несжатыми некоторые из компонентов файла - иконки, информация о версии или любые другие выбранные ресурсы. Кроме сжатия, PECompact позволяет оптимизировать структуру файла и тем самым уменьшить его размер без сжатия (опция Trim Only). Поддерживаются плагины, в том числе и самостоятельно разработанные.
Executable compressors work by compressing selected portions of executables. At runtime, compressed executables are decompressed and reconstructed directly into their virtual image (memory) so that no data is ever written to the disk. The executable can therefore be run exactly as it was before without the user even knowing it was compressed.
PECompact2 is a next generation win32 executable/module compressor. Commonly termed an 'executable packer', such utilities compress executables and modules (i.e. *.EXE, *.DLL, *.OCX, *.SCR). At runtime the compressed modules are rapidly decompressed in memory.
Compatibility:
*
Complete Windows platform support (all variants).
*
Supports EXE, DLL, SCR, and all other Win32 PE formats except device drivers (SYS).
*
Supports software and hardware DEP (Data Execution Prevention).
*
Supports VC++ 7 and 8 (Visual Studio 2003, 2005) CRT SEH protections; currently only win32 packer that properly addresses the issue. This is to say, if your www.luxter.ru C++ exception handling code doesn't work with other packers, it will with PECompact!
*
Compressed programs work under WINE (Windows emulator for Linux).
*
Compressed programs work with NJStar Communicator, ATI OpenGL drivers, and other applications other compressors may fail with.
*
Modules compressed with each build are tested in complex load scenarios under all win32 flavors. Our test cases assure proper functioning.
Anti-Virus Interoperabilility:
*
Viruses can not hide within compressed modules because major anti-virus software support scanning inside the PECompact's modules!
Software Protection:
*
Compressed modules are inherently more difficult to reverse engineer.
*
PECompact support custom loaders that can be written to provide your own unique protection mechanisms, greatly deterring the creation of automatic unpackers.
*
Tampering or modification of modules can be detected at runtime.
*
Plug-ins are available that extend and enhance the protection of your software. These include the FastImport, API Redirect, and IsPacked plug-ins.
Extensibility:
*
A number of plug-in types allow for extreme customization and third-party extensions. For example, plug-ins are included to perform CRC checks, password based encryption, message box runtime confirmations, and compression by a number of different algorithms. And since these plug-ins can be used IN ANY ORDER OR QUANTITY on each and every file, how you use PECompact2 is up to you!
*
Loader and API hook plug-ins can give you custom software protection. No shrink-wrapped software protection mechanism can compete with a custom solution. Custom protection is the best protection. For development of custom loader plug-ins, email us or visit the forum.
