Para un hash codificado en Base64, para validar una firma Oauth, usé 

require 'base64'
require 'hmac-sha1'

Base64.encode64((HMAC::SHA1.new('key') << 'base').digest).strip

He creado un helper gem que es un simple envoltorio alrededor de algún código sha1

require 'rickshaw'
> Rickshaw::SHA1.hash('LICENSE.txt')

 => "4659d94e7082a65ca39e7b6725094f08a413250a" 

> "hello world".to_sha1

 => "2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"

Donde 'serializar' es alguna función de usuario definida en otro lugar.

 def generateKey(data)
    return Digest::SHA1.hexdigest ("#{serialize(data)}")
 end
