- Description
- Finding a preimage for a SHA-1 hash is, at present, a computationally intractable problem. SAT-solvers have been useful tools for handling such problems and can often, through heuristics, generate acceptable solutions. This research examines the intersection between the SHA-1 preimage problem, the encoding of that problem for SAT-solving, and SAT-solving. The results demonstrate that SAT-solving is not yet a viable approach to take to solve the preimage problem, and also indicate that some of the intuitions about “good” problem encodings in the literature are likely to be incorrect.
