RSACtfTool - Retreive private key from weak public key

RSA CTF Tool - Tool to attack RSA public keys and ciphertexts in common ways

Quote:
RSA tool for ctf - uncipher data from weak public key and try to recover private key Automatic selection of best attack for the given public key

Attacks :
  • Weak public key factorization
  • Wiener's attack
  • Hastad's attack (Small exponent attack)
  • Small q (q<100,000)
  • Common factor between ciphertext and modulus attack
  • Fermat's factorisation for close p and q
  • Gimmicky Primes method
  • Past CTF Primes method
  • Self-Initializing Quadratic Sieve (SIQS) using Yafu - NEW
  • Common factor attacks across multiple keys - NEW

New features:
Code:
[*] Small fractions method when p/q is close to a small fraction
[*] Boneh Durfee Method when the private exponent d is too small compared to the modulus (i.e d < n^0.292)
[*] Elliptic Curve Method
