title: Method that converts uint8_t to string
body: <p>I have this:  </p>
  
  <p><code>uint8_t key[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31};</code></p>
  
  <p>How can I convert it to char or something so that I can read its contents? this is a key i used to encrypt my data using AES.</p>
  
  <p>Help is appreciated.
  Thanks</p>
