Python Transposition.decipher Examples

Example #1

File: transposition_bruteforce_attack.py Project: Trindad/trabalhos-seguranca

	def breakOpen(self,enc):

		it = 1
		key = it
		words = 0
		limit = 0
		s = ""

		with open(enc, "r+b") as f:
			while 1:
				data = f.read(1)
				if not data :
			 		break
			 	s += data
		limit = len(s)

		# print limit

		while it <= limit:
			
			transposition = Transposition()
			file = transposition.decipher(enc,it)

			n = self.compare(file)

			# print str(it) + " "+ str(n)
			if n > words:
				key = it
				words = n
			it += 1

		print key
