Lattice Crypto Attacks

yaklang/hack-skills
2.5k installs1.6k stars
Summary

This is a comprehensive playbook for lattice-based cryptanalysis, covering everything from LLL and BKZ reduction basics to practical attacks on RSA (Coppersmith small roots, Boneh-Durfee), DSA/ECDSA nonce recovery via the Hidden Number Problem, and knapsack cryptosystems. The real value is in the attack construction details: proper lattice dimensions, scaling factors, and those subtle beta parameters in Coppersmith methods that base models consistently get wrong. If you're doing CTF crypto challenges or need to attack biased nonces, weak RSA keys, or subset sum problems, this gives you working SageMath and fpylll code with the correct bounds. The routing table at the top is smart too, since these techniques often overlap with other RSA attacks.
