[solved sort of] Some Rules questions with doubling and shifting.

[Skwerl23]

This is sort of interesting. I haven't used John's rules enough to have been familiar with the S rule!

I see that it's not implemented in hashcat. Requesting that via a hashcat GitHub issue might be interesting. If there's a deliberate reason why S isn't supported in hashcat, it can at least be documented there.

I would like to see the ability to use the S rule AND the ability to apply rules to parts of passwords. Like 
d rule to double the password and then S rule to part of a password e.g.
d S{9-16}
So S is applied to characters 9-16
I'll try submitting it on the hashcat GitHub you speak of when I get a minute.
