ModernCryptoLib

ModernCryptoLib is a cryptography library to automate cryptographic attacks.It's main purpose is to help CTF players and advanced users to prevent unauthorized hacks.

Current version

0.0.12

How to install

$ sudo python setup.py install

Initialization

from CryptoLib.RSA import RSA

Example

n = 3233
e = 17
c = 855 #(123 ** e) % n
factordb = RSA.attacks.Factordb(n)
q = factordb[0]
p = factordb[1]
d = RSA.utilities.modinv(e,780)
print "Decrypted Message : {}".format(pow(c,d,n))
