Thanks for your feedback, I updated the description.

Not if you want to be able to retrieve it easily.

The goal here is to have mnemotechnic ideas for passwords, not to generate ones impossible to remember with complex hash functions and salt.
Your method would be interisting server side which was not the goal here.

But thanks.

I know it's just a kata, but something like this would make a much better password generator for use in the real world:

def pwgen(base, sitename, length=12)
  salt = "0beec7b5ea3f0fdbc95d0dd47f3c5bc275da8a33" # must be kept secret
  Digest::SHA1.base64digest(base+sitename+salt)[1..length]
end

pwgen('secret', 'codewars') #=> "X+zJ2Kz2E6DY"
pwgen('secret', 'facebook') #=> "6IH/OuqJrHl+"

Strange. I opened the page again and resubmitted without changes, and this time it worked! I hadn't seen any error messages...
