Silent_Packer

What Silent_Packer is

Silent_Packer is a free, open-source Linux command-line tool written in pure C for obfuscating ELF and PE binaries. It supports PIE binaries and works by encrypting a binary's .text section, then decrypting it before execution. Supported formats are ELF64, ELF32, PE32+, and PE32, covering 32-bit and 64-bit architectures. Users can choose XOR or AES-128-ECB and select Section Insertion, Code Cave, or Silvio Text Infection; the last method is limited to ELF files. Command-line options cover input and output files, cipher and packing method selection, plus help, version, verbose, and debug options. Building from source requires cmake, gcc, and nasm. The project is licensed under GNU AGPLv3, and its README invites bug reports and suggestions for additional formats or cipher methods. It describes the intended use as professional or educational. The README says there is no Windows version. It also reports recurring PE file bugs, especially with large binaries that have many dynamic libraries, and occasional offset problems with Section Insertion. The releases page lists version 0.1 as the latest release.
