  • Small Exponent Attacks: Exploits small exponents in RSA to recover plaintext, such as the Cube Root Attack and Hastad Broadcast Attack.
  • Lattice-Based Attacks: Utilizes lattice reduction algorithms like Wiener's Attack, Boneh-Durfee Attack, and Coppersmith's Method for larger modulus factorization.
  • Oracle Attacks: Includes attacks like the Bleichenbacher Attack and LSB Oracle Attack that exploit padding oracles in RSA encryption.
  • Fault Attacks: Provides techniques for factoring RSA modulus from faulty signatures or faulty computations.

Quick Start

Use the rsa-attack-techniques skill to factor the RSA modulus from the provided public key and ciphertext.

Frequently Asked Questions about rsa-attack-techniques

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I recover plaintext from an RSA encrypted message using cryptanalysis?▼

You can recover RSA plaintext by applying cryptanalytic techniques like factorization, small exponent exploits, lattice reduction, and oracle attacks against the provided ciphertext and public key.

What is a lattice-based attack and when do I use it for RSA factorization?▼

A lattice-based attack uses lattice reduction algorithms like Wiener's Attack, Boneh-Durfee Attack, and Coppersmith's Method for larger modulus factorization when standard factoring approaches are computationally infeasible.

Can I use Sage and sympy to perform a Bleichenbacher padding oracle attack?▼

Yes, you can use Sage and sympy dependencies to perform a Bleichenbacher padding oracle attack, which exploits padding oracles in RSA encryption to gradually recover plaintext.

How do I factor an RSA modulus with a small public exponent?▼

You can factor an RSA modulus with a small public exponent by applying small exponent attacks like the Cube Root Attack and Hastad Broadcast Attack, which exploit weak exponent configurations to recover plaintext.

Do I need to know specific cryptanalytic methods to use these RSA attack techniques?▼

Yes, applying these RSA attack techniques requires existing knowledge of RSA and various cryptanalytic methods, as the implementation is designed for cryptographic analysis tasks in CTF competitions and security assessments.
