Open-source alternatives to Skycript

RsaCtfTool is a specialized cryptography suite designed for solving capture-the-flag challenges. It serves as a cryptanalysis and key recovery tool used to derive private keys and decrypt data from weak RSA public key implementations. The tool functions as an integer factorization toolkit, employing a variety of mathematical attacks and algorithms to decompose large composite numbers into their prime factors. It integrates with external prime number databases to accelerate the factorization process and identifies specific mathematical vulnerabilities in key generation. Its capabilities cover
