DEScrypt： A hash collision security research tool based on CPU

DEScrypt uses a two-byte salt (composed of characters [a-zA-Z0-9https://www.freebuf.com/articles/database/][1]) by default, which means that we need to generate about 65536 unique rainbow tables, so the efficiency of using DEScrypt's collision cracking to find plaintext passwords will be higher.

Function introduction

1, Can crack hashes based on file or single input;

2, Support detecting CPU cores;

3, Support adjusting the number of threads;

4, Support comma-separated output files;

5, Clear and readable output display;

6, The average hash rate of 10 threads on a single CPU core is 22000 per second by default;
