GitHub Stats
About Hashcat
Hashcat is the world's fastest and most advanced password recovery utility, supporting over 300 highly optimized hashing algorithms. It leverages GPU acceleration to crack hashes at unprecedented speeds. Hashcat supports multiple attack modes including dictionary attacks, brute-force, combinator, mask attacks, rule-based attacks, and hybrid attacks. It runs on Linux, Windows, and macOS and supports every major GPU vendor.
About RsaCtfTool
RsaCtfTool is a comprehensive RSA attack tool that implements dozens of known attacks against weak RSA public keys to recover private keys and decrypt ciphertext. It supports attacks including Wiener's continued fraction method, Boneh-Durfee, Fermat factorization, Pollard's p-1 and rho algorithms, common modulus attacks, and many more cryptographic weaknesses that appear in CTF challenges and poorly implemented real-world systems. CTF players, cryptography students, and security researchers use RsaCtfTool to rapidly test RSA key pairs against a battery of known attacks, automatically identifying and exploiting weaknesses without requiring deep mathematical expertise. The tool accepts public keys, ciphertext, and various RSA parameters as input and attempts all applicable attacks in sequence, making it an essential utility for anyone working with RSA in competitive or educational security contexts.
