A utility that attempts to decrypt data from weak RSA public keys and recover private keys using multiple integer factorization algorithms.
RsaCtfTool is a utility designed to decrypt data from weak RSA public keys and attempt to recover corresponding private keys. The tool combines multiple integer factorization algorithms to enhance decryption capabilities against RSA encryption. The tool focuses on exploiting the complexity of the integer factorization problem that underlies RSA security. It offers various attack strategies and methods for attempting to crack RSA encryption, particularly targeting weak implementations. RsaCtfTool is primarily intended for educational purposes and CTF competitions. The tool supports RSA textbook semiprime composite modulus but does not support composite multiprimes due to upstream limitations in the pycrypto library. Users should note that not every RSA key can be broken within a reasonable timeframe, as the complexity of properly implemented RSA encryption presents significant computational challenges. For more advanced integer factorization requirements, the tool documentation recommends using specialized tools like msieve or yafu.
