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.
