Crack Me 2

Table of Contents

Simple SHA3-512.

Problem

Here’s another one.

Hash: b1ee3fbc44b4ba721273699ac4511fa1631257f37da7bede3d5ba7bda5e7f96f1bab30e206caf47a5ce8c6587d0fbd6306e70b08a3a7e7233bb707bf21752c33

NOTE: The flag is NOT in the standard auctf{} format

Result

 ./hashcat-5.1.0/hashcat64.bin -a 3 -m 17600 b1ee3fbc44b4ba721273699ac4511fa1631257f37da7bede3d5ba7bda5e7f96f1bab30e206caf47a5ce8c6587d0fbd6306e70b08a3a7e7233bb707bf21752c33 -O

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework

Cracking performance lower than expected?

* Append -w 3 to the commandline.
  This can cause your screen to lag.

* Update your OpenCL runtime / driver the right way:
