    object which will write the Base64 encoding of the byte array
    Since:
    1.0
  - public static Writable encodeBase64(byte[] data, boolean chunked)
    
    Produce a Writable object which writes the Base64 encoding of the byte array. Calling toString() on the result returns the encoding as a String. For more information on Base64 encoding and chunking see RFC 4648.
