salty

stupid little gem for salted hashing (for, eg, user passwords)

Installation

Just

$ gem install salty

and you’re good.

If you want, you can also just

$ wget https://raw.github.com/alecbenzer/salty/master/lib/salty.rb

and get the file locally. It’s less than 1KB.

Usage

require 'salty'  # you may need to do './salty' if you used wget

password = Salty.hash('mypassword') # iterative salted SHA512 hash

if Salty.check('mypassword',password)
  puts "You're logged in!"
else
  puts "Wrong password"
end

A salt is generated and embeded in the output from Salty.hash. Salty.check will then extract this salt, so there is no need to handle the salt yourself.

Obviously, the order of arguments to Salty.check is important. The plain-text data must come first, followed by the previously-hashed data.
