Such a brute-force attack is based on the birthday paradox, and it would require expected 2^80 computations to produce a SHA-1 collision. Of course, collisions should also be computationally infeasible to find in practice.

What you want to know is the chance of someone sharing a birthday (hash value) with you. WebThat means it takes about 2 n − 1 tries on average to find a colliding message y for a given message x so that H ( y) = H ( x) while y ≠ x. However, a birthday attack (e.g. both x and y can be selected arbitrarily, but H ( x) = H ( y) is of course still required) is supposed to be much faster, and take only 2 n / 2 tries to find a collision.

WebTherefore, the probability that two people have the same birthday is 1- 0.492703 = 0.507297.
