This Skill provides a comprehensive set of tools and techniques for attacking cryptography challenges in CTF competitions, covering a wide range of cryptographic primitives and attacks.
Use the ctf-crypto skill to analyze a given RSA public key and attempt to factorize the modulus to recover the private key.
High-intent search queries and answers about installing and using this skill.
To factorize an RSA modulus, you can apply Coppersmith's method or lattice-based attacks like LLL and BKZ. This Skill provides scripts using sympy and gmpy2 to recover the private key from a given RSA public key.
Solving LWE and lattice problems involves applying LLL, BKZ, and Babai's algorithm for CVP. This Skill integrates fpylll to execute these lattice-based attacks and compute the underlying lattice constraints.
Yes, you can use the Z3 solver for symbolic computation to attack zero-knowledge proofs and solve constraints. This Skill leverages z3-solver to automate the constraint solving process for complex cryptographic scenarios.
Yes, attacking modern ciphers like AES and ECC is fully supported. This Skill provides techniques for padding oracle attacks, S-box collisions, and ECC analysis using pycryptodome and py_ecc libraries.
You need sagemath and hashcat alongside dependencies like pycryptodome and fpylll to execute these cryptography attacks. They provide the mathematical computation and hash cracking capabilities required by the scripts.
