Bitsum PECompact

Bitsum PECompact — утилита для сжатия файлов EXE, DLL, SCR, OCX с сохранением их полной работоспособности. В первую очередь предназначена для разработчиков программного обеспечения, позволяя им сжимать информацию и код, делая исполняемые файлы меньше по размеру. Для сжатия, программой используется оригинальный алгоритм сжатия JCALG1, позволяющий значительно уменьшать размер исполняемого файла. Допускается оставлять несжатыми некоторые из компонентов файла — иконки, информацию о версии или любые другие выбранные ресурсы. Кроме сжатия, PECompact позволяет оптимизировать структуру файла и тем самым уменьшить его размер без сжатия.

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.

There are many reasons. One of the most common is that compression offers an inherent degree of tamper resistance and obfuscation. Another is that since the usual compression ratio is greater than 70% (that is, the compressed file is 30% of the original), larger executables and modules may load much quicker from the network or disk hosting them. Since storage medium is often the largest bottleneck in overall system performance, the time spent decompressing can be much less than the time saved by not having to load as much data from the storage medium.

PECompact2 is a utility of the genre known as "executable packers". Executable packers compress executables and modules so that their physical size is considerably smaller than it originally was. At runtime, the module (executable) is decompressed and reconstructed in memory. With high-performance executable packers such as PECompact v2.x, decompression and reconstruction is so rapid that load time may actually improve since the time saved by reading fewer bytes from the disk or network may exceed the time spent reconstructing and decompressing the module.

Typically, PECompact2 compresses modules substantially better than that of the common compression software such as RAR and ZIP. This is accomplished through advanced techniques of pre-processing a module to make it more compressible when passed to the compression algorithm. PECompact2 allows use of virtually any compression algorithm due to its CODEC plug-in support.

In addition to space savings, PECompact2 inherently makes it more difficult to reverse engineer your module(s). The compressed data is unreadable and not directly modifiable. PECompact2’s default loader employs some basic anti-debugging code to aid in prevention of reverse engineering. In addition, PECompact2 supports Loader plug-ins. Therefore, third parties can create custom loaders after purchasing the loader SDK.

PECompact2 — это утилита, относящаяся к классу так называемых "упаковщиков исполняемых файлов". Такие упаковщики предназначены для сжатия исполняемых файлов и модулей с целью существенно уменьшить их физический размер. При запуске сжатый модуль (исполняемый файл) распаковывается и в памяти воссоздаётся его исходный вид. При использовании высокоэффективных упаковщиков (например, PECompact версии 2.x), распаковка и воссоздание файлов происходят столь быстро, что в результате время их загрузки может даже сократиться, так как время, сэкономленное на чтении меньшего количества байт с диска или из сети, может оказаться больше времени, затрачиваемого на распаковку и реконструкцию модуля.

Как правило, PECompact2 сжимает исполняемые модули заметно лучше, чем популярные программы-архиваторы вроде RAR и ZIP. Это достигается благодаря тому, что модуль проходит предварительную обработку, в результате которой он становится более плотно сжимаемым при передаче алгоритму компрессии. PECompact2 позволяет применять практически любые алгоритмы сжатия, поскольку использует механизм кодеков-плагинов (внешних подключаемых модулей).

Помимо сохранения места, PECompact2 также осложняет несанкционированную модификацию ваших модулей и восстановление алгоритма их работы. Сжатые данные нельзя прочесть или изменить напрямую. Стандартно используемый в PECompact2 загрузчик содержит несложный код против отладчиков, препятствующий восстановлению алгоритма. Кроме того, PECompact2 поддерживает плагины-загрузчики, т.е. вы можете сами создавать свои загрузчики, приобретя соответствующий набор инструментальных средств разработки (SDK).

PECompact имеет возможность работы с плагинами, позволяющими пользователю программы дополнять сжимаемые файлы новыми функциями или применять к ним процедуры шифрования. Также имеется поддержка работы в командной строке и функция оптимизации исполняемых файлов без компрессии. Программа написана на ассемблере и предоставляет пользователям возможность детальной настройки своей конфигурации в меню параметров для выбранных файлов.

PECompact is a utility that compresses Windows 9x/NT4/w2k portable executables (EXE, DLL, SCR, OCX, etc..) significantly while leaving them 100% functional.

Compress - Protect - Encrypt - Optimize - Customize

Compresses tighter than the latest versions of all commercially viable executable compressors.

PECompact processed applications occupy less disk space, cost less to distribute, are more fault tolerant, are loaded quicker across networks, decrease network traffic, and are more difficult to reverse- engineer and modify.

PECompact works by compressing the code, data, import directory, selected resources, and other portions of Windows portable executables.

At runtime, the executable is rebuilt in memory with no noticeable delay; the executable is at no time extracted to disk. In fact, compressed executables can actually load quicker in some cases because there is less data to be retrieved from the disk or network, which is usually the largest bottleneck.

Both compression algorithms used by PECompact feature an optimized, 32bit x86 assembly language decompressor for maximum data throughput. This tool is highly configurable and gives the user a great deal of power to select what and how things are compressed.

PECompact also has unique plug-in support to allow users to supply their own encryption/decryption procedures or special functionality to compressed executables.

For users who prefer not to compress their executables for whatever reason, PECompact also offers a "Trim Only" option that optimizes the executable structure and decreases its size without applying any compression at all! This function can optionally strip relocations from the executable.

Complete win32 platform support (all variants).

Supports EXE, DLL, SCR, and other PE formats.

Supports software and hardware DEP (Data Execution Protection).

Supports VC 7.1 (Visual Studio .NET 2003) SEH protections; currently only win32 packer that properly addresses the issue.

Compressed programs work under WINE (Windows emulator for linux).

Modules compressed with each build are tested in complex load scenarios under all win32 flavors. Our test cases assure proper functioning. Up to date and actively being improved!

Viruses can not hide within compressed modules because major anti-virus softwares support scanning inside the PECompact 's modules!

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.

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 PECompact 2 is up to you!

PECompact is superior to its competitors in many ways, many already enumerated above. Most striking is its performance, configurability, compatibility, and stability. When using PECompact you can rest assurred that your application is compressed using an executable compressor that is used on software running on millions of computers worldwide. Our clients include Google, Microsoft, and many others.

Compresses Windows executables significantly, while allowing them to be run as normal, in order to free up space on the hard disk

With the help of PECompact you can reduce the size of Windows executables, without corrupting the files. It supports EXE, DLL, SCR, OCX and other formats, and primarily caters to advanced users.

The interface is based on a standard window with a plain layout, where you can import files using either the file browser or drag-and-drop support.

You can view the type, original and new size, compression ratio, file path, and selected options for each file, along with additional information (e.g. extra data appended).

As far as settings are concerned, you can ask PECompact to compress or only trim the files, embed a numerical watermark, allow multiple compressions, compress exports, create backups, as well as to emulate overlay or extra data.

In addition, you can apply a plugin (e.g. anti-debug), use the Windows DLL loader, strip fix-ups, unused resources and the debug data directory, select API hook plugins, select the resources to compress, adjust the compression level and use fast decoders, as well as perform a code integrity checkup, among others. Options can be restored to their default values.

Furthermore, you can test selected executable files and restore backups if any errors occur. The tool quickly finishes a task and delivers good results. However, it failed in its attempt to restore backups on multiple occasions in our tests.

PECompact uses low CPU and RAM, so it doesn't affect overall performance. It is also able to integrate into the Explorer context menu. Unfortunately, it has not been updated for a long time, and the utility has compatibility issues with newer operating systems. Other than that, PECompact provides an efficient method for compressing executable files to free up space on the hard drive.

• and more.

  There are many more plug-ins, both third-party and developed by Bitsum.

Powerful executable compression for software developers and vendors

PECompact has been a leader in the Windows executable compression industry for over a decade. You'll find no other compressor that offers the features of PECompact. Software distributions large and small have used PECompact. For instance, Google Desktop and DiVX Player.

Software vendors will want to compress their Windows executables for a wide array of reasons, but the usual reason is to help protect the code and data inside. Compression inherently does this, though it is no fool-proof solution (no fool-proof solution is possible). PECompact is technically a Windows executable compressor only, but plug-ins are available for it that offer protection against reverse-engineering (some sold separately by third-parties).

If you don't care about your data security, then perhaps you may need to reduce EXE size even further than archivers like ZIP and RAR can achieve. Since our algorithm is optimized for PEs, we pre-process the code using advanced algorithms that make it more compressible for dictionary based compressors like LZMA.

Decreasing your EXE size can actually speed load time because the retrieval time from the storage media or network is often greater than the very rapid decompression time. Pages that are not used will quickly get paged out by Windows as needed, then your application will be running just as if it were never compressed. Shared sections of your PE are skipped by default and your EXE still makes full use of shared system DLL pages. So, there is only upside on the performance side of the equation.

Ok, so you want to compress, but need to pick a compressor. There is UPX, Aspack, and PECompact. Those are the top 3 PE (32-bit) native EXE compressors. UPX has a decompression switch and is open source (often abused by malware authors), Aspack can not compress as well as PECompact and has no plug-in support at all. It also lacks other key features of PECompact. We invite you to try them all for yourself, as we're confident you'll come back to PECompact if you are 'our type of customer'.

To get to the question of Why PECompact? The answer is its maturity, interoperability, compatibility, and compression ability. You want a Windows executable (PE) compressor that has been around for a while and is supported by all the popular security software. That way, the security products can scan inside your EXE. This keeps the bad guys from using the compressor, and maintains all the benefit for the good guys. This is important, because if a security product can't see inside the EXE, it will often just mark it as suspicious. We work hard to achieve good interoperability with all the major security software companies.

PECompact's compression ratio is second to NONE. Our record speaks for itself. Compare us yourself. We pack better than ASPack, much better than PEtite, and compress as well as UPX (but don't have that 'decompress' switch that UPX has). We keep your code and data compressed as good as it can be, offering the perfect mix of security, stability, and interoperability. Our compress executables work everywhere and require no modifications.

PECompact does things right. For instance, it skips shared sections of DLLs by default, and can skip any shared section -- allowing you to maintain memory sharing between process instances. It makes sure icons needed for use by the shell are kept uncompressed, so your shell view icons don't disappear. It makes sure version and manifest information is also kept uncompressed, and can keep any other type of resource you desire kept uncompressed. Additionally, it is the ONLY compressor that properly preserves debug information embedded in the PE. Naturally, it fully supports software and hardware DEP as well as code signing (after compression).

• Great compression

PECompact *IS* fully compatible with DEP, code signing (sign after compression), and Windows 7/2008. We keep PECompact well maintained. It supports native PE modules, but does not support device drivers or some .NET assemblies. PE+ (PE64) support is still pending as it requires a massive rewrite of the loader (decompression stub).

PECompact is available in English, Russian, Chinese (traditional and simplified), German, Dutch, French, Swedish, Italian, Slovenian, and Polish!
