body: <p>I'm trying to store a raw OpenSSL cipher key inside rails credentials file but, during the retrival, value gets escaped and it's not working anymore when i try to use it as an actual key.</p>
  <pre><code># credentials.yml
  cipher_key: &quot;\xCC\x7Ft%\xEA\xAD\x15u^\xB9W1\xB2m\x7FDZr\x04C\xE24\x93\xCFz4\x89\x7F-g\xBE5&quot;
  
  # Rails console
  3.1.1 :001 &gt; Rails.application.credentials.cipher_key
   =&gt; &quot;Ì\u007Ft%ê­\u0015u^¹W1²m\u007FDZr\u0004Câ4\u0093Ïz4\u0089\u007F-g¾5&quot;
