How many different ways can 5 people be seated on a bench ?
Answer: 5! 5x4x3x2x1 = 120 There is 120 possibilities.
How many different ways to order the pixels in a Kodbild ?
Answer: The format is : 1350 x 900 = 1 225 000 pixels. 1 225 000! = Infinity.
The number of combinations of pixels in a Kodbild is infinite.
On the other hand, the number of hash SHA256 is not.
If multiple computers are used simultaneously, the process of brute force can be accelerated.
See the Graphic one above, with 4 computers (0, 1, 2, 3).
The black circle represents all the exaustive number of combinations SHA256.
The decipherer has two difficulties:
-First difficultie: he does not know what he is looking for:
-Second difficulty: the person decoding must know the exact number of loops
Conclusion: Force brute remains however doable. Try all SHA256 combinations with different loops.
Prevent force brute
Against brute force, I apply the double coding of the same image with two different seeds.
