Longshot enables to search for preimages from a given hash value using a brute-force method based on parallelism. Support various search lengths, character sets and hashers Strict mode: searches only for a given exact length Deep mode: Incrementally searches when you do not know the exact length of search Use CPUs as much as possible. Get the most out of them! Use, however, memory as little as possible. Please see the documentation at https://github.com/thyeem/longshot for usage example.
