Convert byte[] to String when you send Signature in http header

byte[] signatures = ...
String signatureAsString = BaseEncoding.base64().encode ( signatures );
// Add signatureAsString as a HTTP header X-SIGN

To get signature in Http Header in Servlet Filter

// ServletRequest request
HttpServletRequest req = (HttpServletRequest)request;   
String signature = req.getHeader("X-SIGN");
byte[] bytes = BaseEncoding.base64().decode ( signature  );

I used Google Guava BaseEncoding for encoding/decoding. You can use any Base64, Base16 encoding API.
