seakg-hack-xor

1. Encrypt/Decrypt file use a xor
2. Try hack xor crypt

Concept of hack: Filtering possible key values based on a specific alphabet of the initial file and key length.

Build

Requirements for build (MacOS):

$ brew install pkg-config cmake

Requirements for build (Ubuntu/Debian):

$ sudo apt install cmake make g++ pkg-config git-core

Integrate to your project via wsjcpp

$ wsjcpp install https://github.com/sea-kg/seakg-hack-xor:master

or include files:

• src.wsjcpp/wsjcpp_core.h
• src.wsjcpp/wsjcpp_core.cpp
• src/seakg_hack_xor.h
• src/seakg_hack_xor.cpp

Run && Usage

Crypt file

$ ./seakg-hack-xor xor orig_filepath key_filepath crypted_filepath

Decrypt file

$ ./seakg-hack-xor xor crypted_filepath key_filepath decrypted_filepath

Try hack crypted file example run and output

$ ./seakg-hack-xor xor crypted_filepath 38 key_alphabet_filepath text_alphabet_filepath
