class HMAC::SHA384 - ruby-openid-2.9.2 Documentation

Source

# File lib/hmac/hmac.rb, line 88
def Base.digest(key, text)
  begin
    hmac = self.new(key)
    hmac.update(text)
    hmac.digest
  ensure
    hmac.reset_key
  end
end

These two class methods below are safer than using above instance methods combinatorially because an instance will have held a key even if it’s no longer in use.
