Hi, newbie question about maximum salt lengths here.
I am trying to crack some sha256 salted hashes. When first trying to learn hashcat, I ran it on my CPU-only Ubuntu desktop using a 5.4 kernel, and my hashcat startup message said the kernel supported salts up to length 256. Awesome!
But once I moved my cracking project over to a AWS instance with a GPU and running ami-0fe5363b80d5bb2da, the startup message said it supported salts up to length 51. Uname -r reports that this is a 5.15 kernel.
What kernel version do I have to get to to get back to maximum salt lengths of 256? Are there any other software or hardware constraints that govern this maximum, or is this limit strictly based on kernel version?
Thanks in advance!
PS: Apologies if this was in the FAQ and I missed it. And by the way, that is a truly amazing FAQ.
