Eyal The Singer
build status

This is a password-cracking tool built for paralellization across CPU, GPU and possibly multiple devices connected on a network.

The tool is based on brute-force and does not use any sort of weakness in the underlying mechanisms.

⚠️ This is created for educational purposes only. The code is provided without any guarantees and the person running the code bears all responsibility.

Features

  • Cipher support
    • SHA256
    • SHA1
    • WPA2
  • Parallelization support
    • CPU parallelization
    • CUDA
    • Multiple devices

Demo

Cracking Basic Ciphers

  • Run eyalthesinger download rockyou.
  • Run eyalthesinger crack sha256 rockyou.txt 3de3311f7965ecad3ff387be58e223acdfbaaef359a4bc1209284593dd76c15b.

Cracking WPA2

  • Get a pcap containing a 4-way handshake.
  • Run eyalthesinger format wpa example.pcap.
  • Run eyalthesinger download rockyou.
  • For example, run eyalthesinger crack wpa rockyou.txt 4275696c64696e675f473200:20c19b58d6a3:28b37120f22c:3f045e6b81f56f7cebbbdbb9dbfb62b3db8a392c339962b1b5a3addfc2e397b0:5835a601df741dcf5f50495ba70dd8745a739e6770e0daf8ccda88010009c271:0103007502010a000000000000000000013f045e6b81f56f7cebbbdbb9dbfb62b3db8a392c339962b1b5a3addfc2e397b0000000000000000000000000000000000000000000000000000000000000000071b1942d7ad8f86e6c288ae3f61c2ec7001630140100000fac040100000fac040100000fac028000:71b1942d7ad8f86e6c288ae3f61c2ec7.

Networking

  • Run eyalthesinger server.
  • Run eyalthesinger connect (if you have multiple devices on the network, connect the others as well).
  • In the server, run download rockyou.
  • In the server, run crack sha256 rockyou.txt 3de3311f7965ecad3ff387be58e223acdfbaaef359a4bc1209284593dd76c15b.

Development Setup

  • Install rye.
  • Run rye sync and use the virtual environment created in .venv (i.e. source .venv/bin/activate or .venv\Scripts\activate).
  • Compile the CPU crackers by running clang -O3 crackers/*.c -I. -o sing (or gcc -O3 crackers/*.c -I. -o sing).

Eyal the Singer was built as part of the Workshop in Implementation of Cryptographic Attacks at Tel Aviv University, hosted by Dr. Eyal Ronen.
