/**
 * shiro1 cracking snippet
 * So apparently hashcat and JtR don't support these kind of specific hashes
 * with salt and iterations so I needed to code my own.
 * It has shit performance, code is probably retarded; I don't do java so I just
 * hacked this to verify a hash I dumped from Sonatype Nexus wasn't in a basic dictionnary.
 * And if you're here you likely can't afford to be picky...
 * Based on this snippet: https://gist.github.com/mdeggies/cdfd22a9cf28b4e909489b877681a209
 *
 * Usage:

gquere

/**
 * gcc shiro1.c -lcrypto -lssl -fopenmp
 *
 * Crack salted iterated SHA512 hashes.
 * Just wanted to check how much faster it was rather in C than in Java:
 *      https://gist.github.com/gquere/365cfcceef9ac8d145cc59bbf2c27648
 *
 * Here are the results I got using rockyou, 1024 iterations, so about 15 billion hashes:
 * time ./a.out ../rockyou.txt
 * 8130,86s user 1,05s system 787% cpu 17:12,07 total
