Using JSON Objects to store encrypted data

Question

I am currently writing java client and server chat application using socket programming in which I am exchanging data using JSON objects.When I try to store byte array containing encrypted data, and sends udp data packet from client to server, byte data gets corrupted.

As per few posts, JSON object cannot handle byte array data. So is there any way by which I can send multiple encrypted data byte arrays using UDP packet from client to server?

JSON objects absolutely can handle byte arrays. Here is one example using Jackson. — Vidya

but is same possible with encrypted data also as it contains many illegal characters? — Frankenstein

You should encode the binary data in a printable form, i.e. Base64. See stackoverflow.com/a/2054226/18157 — Jim Garrison

As noted in the comments, you can encode binary data as text, using the very old and well-known technique of Base64 encoding. In Java you can do this using javax.xml.bind.DatatypeConverter.
