Answer 1

This might be of help for those using Java 8. Make use of java.util.Base64.

Encoding byte array to String :

String encodedString = java.util.Base64.getEncoder().encodeToString(byteArray);
JSONObject.put("encodedString",encodedString);

Decode byte array from String :

String encodedString = (String) JSONObject.get("encodedString");
byte[] byteArray = java.util.Base64.getDecoder().decode(encodedString);
