Hello Guixers!

Attached you will find my first patch submitted here in awhile! I'm hoping I've followed the guidelines, they haven't really changed much that I can see. Also, if I incorrectly attached the file, do tell, as I'm on a new (Emacs + notmuch) email workflow!

Unfortunately, I wasn't able to get hashcat to build reproducibly, and I'm not sure why, but 1) the 6.1.1 version wasn't reproducible, and 2) it's literally just a few bytes.
