Enigma Virtual Box vs Windows PE Packer

Enigma Virtual Box packages an application's files and registry into one executable for Windows. It is intended for creating portable applications and supports x86 32-bit and x64 64-bit binaries, including EXE, DLL and OCX formats. It can virtualize DLLs, ActiveX/COM objects, media and text files. Virtualized file operations are emulated in process memory, so temporary files are not extracted to the hard drive; virtual files can also be compressed to reduce the application's total size. ActiveX/COM components can be registered without administrator privileges. The maker says packaging requires no source-code changes: select the main executable, add files or directories, then process them. The download page lists version 11.30 as freeware with a size of 7.5 Mb, and the product page lists Windows 2000 through Windows 11. The maker cautions that the utility does not provide sufficient protection for virtualized files and recommends Enigma Protector for that purpose. It is free, with no registration or payment required.

Windows PE Packer is a free, MIT-licensed command-line project that packs Windows PE files to obstruct some forms of reverse engineering. It changes the import table, encrypts sections, clears section names, and adds a shell-entry. When a packed program runs, that entry decrypts the sections, initializes the original import table, and performs relocation. The project says this can make disassembly, constant-string searches, and import-table analysis more difficult. Its command takes an input filename and an output filename: PE-Packer . It currently handles only 32-bit.exe programs and must be configured for 32-bit Windows. Building it requires MASM32, MinGW-w64 with i686 architecture, and CMake. Written in C and Intel x86 Assembly, it is described by its maker as a beginner demonstration for learning about the Windows PE format and assembly; compatibility problems and bugs make it unsuitable for practical use. The repository lists no releases. The MIT license permits copying, modification, distribution, and other uses subject to its conditions, and provides the software without warranty. The plan is free.
