Thanks for explaining! I just can&#x27;t understand how such &#x27;solvers&#x27; can help with crypto, when strong crypto-algos are not reversible and hence there is no point to approach them backwards?<p>If any algorithm can be weakened by such &#x27;problem solvers&#x27;, it wouldn&#x27;t be considered strong? For instance, can SHA256 be reversed (i.e. collision found) faster with such a solver? I guess not..<p>I realize that with crypto, solvers can optimize the flow of the algorithm, make it more efficient and omit repeating some code parts, but a good bruteforcer written in assembly can be as optimized..?
