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.
