RSA-Common-Modulus-Attack

Python ★ 41 via github-topic

RSA-Common-Modulus-Attack is a Python 3 script designed to exploit the common modulus vulnerability in RSA encryption by recovering plaintext messages from two ciphertexts encrypted with the same modulus but different exponents. The tool requires the public keys of both ciphertexts and operates under the condition that the greatest common divisor of the two exponents is 1. Notable features include a simple command-line interface for inputting ciphertexts and public keys, as well as dependency management through a requirements file for easy installation.
