PECompact 2.80 Beta 7

Posted on May 10th, 2008 by admin, under software.

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

Compress - Keep - Encrypt - Improve - Customize

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

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

PECompact 2.80 Beta 7 works by compressing the code, info, import folder, 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 indeed load quicker in some cases because there is less info to be retrieved from the disk or network, which is usually the largest bottleneck.

Both compression algorithms used by PECompact 2.80 Beta 7 highlight an optimized, 32bit x86 assembly language decompressor for maximum info throughput. This utility is highly configurable and gives the PC user a great deal of power to select what and how things are compressed.

PECompact 2.80 Beta 7 also has unique plug-in maintenance to let PC users to supply their own encryption/decryption procedures or special functionality to compressed executables.

For PC users who prefer not to pack their executables for whatever reason, PECompact 2.80 Beta 7 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.

Codec Plug-ins: LZMA - FFCE - aPLib - JCALG1 - BriefLZ
Other Codec Plug-ins: Pass Keep - MessageBox - Invert - Copy - Expand
API Hook Plug-ins: Fast-Import - Redirect
Loader Plug-ins: Anti-Debug - Debug - Enhanced Anti-debug - Reduced

Main features:

• Complete win32 platform maintenance (all variants).
• Supports VC++ 7.1 (Visual Studio safety.NET 2003) SEH protections; currently alone win32 packer that properly addresses the issue.
• Tampering or modification of modules can be detected at runtime.
• Modules compressed with each build are tested in complex load scenarios under all win32 flavors. Our diagnostic cases ensure pertinent functioning. Up to date and actively being improved!
• Plug-ins are accessible that extend and enhance the shield of your software. These include the FastImport, API Redirect, and IsPacked plug-ins.
• Compressed modules are inherently more arduous to reverse engineer.
• Compressed programs work under WINE (Windows emulator for linux).
• PECompact 2.80 Beta 7 maintenance custom loaders that can be written to provide your own unique shield mechanisms, greatly deterring the creation of automatic unpackers.
• A number of plug-in types let for extreme customization and third-party extensions. For example, plug-ins are included to accomplish CRC checks, pass 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!
• Viruses can not hide within compressed modules because major anti-virus softwares maintenance scanning inside the PECompact’s modules!
• PECompact is superior to its competitors in a lot of ways, a lot of already enumerated above. Most striking is its performance, configurability, compatibility, and stability. When using PECompact you can rest assurred that your programm is compressed using an executable compressor that is used on software running on millions of computers worldwide. Our clients include Google, Microsoft, and a lot of others.
• Supports software and hardware DEP (Data Execution Protection).
• Supports EXE, DLL, SCR, and other PE formats.
