PECompact vs Windows PE Packer

PECompact has no write-up on Specifiction yet; its figures are above.

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.
