title: Is there a way to decrypt an encoded string without a key in Ruby?
body: <p>Here's the problem, a string has been passed through three separate encryptions in the following order: Original -> Base64 -> AES-256 -> Blowfish (Keyless) -> Final. Write a method that takes this triple encoded string <code>mystery_string = "OXbVgH7UriGqmRZcqOXUOvJt8Q4JKn5MwD1XP8bg9yHwhssYAKfWE+AMpr25HruA"</code> and fully unencrypts it to its original state.</p>
  
  <p>I looked into different libraries/documentation for aes256 and blowfish but all of them required a key. The only one that did not require a key was Base64 (i.e. <code>Base64.encode64('some string')</code> ). Not really sure where to go from here.</p>
