title: How to convert byte array into Human readable format?
body: <p>I am using "Blowfish" algorithm to encrypt and decrypt the contents of the text. I am embedding the encrypted contents in the image but while extracting I am getting the byte array which I am passing it to method <strong>update</strong> of class <strong>Cipher</strong>.   </p>
  
  <p>But the method returns me byte array which I want to convert back into Human readable form.<br>
  When I use <strong>write</strong> method of <strong>FileOutputStream</strong> it is working fine when a filename is provided.<br>
  But now I want to print it on the console in the human readable format.  How to get through this? I have tried for ByteArrayOutputStream too. But didn't work well.  </p>
  
  <p>Thank you.</p>
