AlushPacker vs BoxedApp Packer

AlushPacker is a Windows utility for packing native Portable Executable (.exe) files for in-memory execution. Its builder compresses files with LZAV and encrypts them using a custom XTEA implementation. When run, its reflective loader decrypts and decompresses the embedded executable, then loads it from memory without disk I/O or assistance from the Windows loader. The project says packing can make static analysis and reverse engineering with tools such as IDA Pro or Ghidra more difficult. Listed support covers x86 and x64, including native console, GUI, and legacy EXE files. The loader resolves normal and delay-loaded imports by name or ordinal and supports relocations, SEH registration, and TLS callbacks. An optional -l key setting makes the output request a password before execution. The release ZIP contains packer.exe for generating packed executables. The source is available under the MIT License, which permits use, modification, distribution, sublicensing, and sale subject to its conditions. The project welcomes code improvements, bug reports, and feature suggestions for maintainer review.
