SHA1 collision finder

From a generated SHA1 string (like 769b87a24a8a5f25dcec396dc6a66ee82fa2ccb1 ) we need find a collisions.

The original string can be variable size (from 32KB up to 512KB), you will have this original string to find a collision.

The objective is give two strings of same size that generates the same SHA1 hash.

Requirements:

-Developed in python or C

-We can use GPU to process data.

Készségek: C programozás, Linux, Python, Szoftverarchitektúra, Szoftvertesztelés

Hello. I can make a program that tries to find collisions but I cannot assure it will actually find one. The likelihood of two equal sized strings to share the same SHA1 string is in the order of 10^-45. That is... Több
