I couldn't think of a simpler way to do it than you have. I base 64-encoded the 2 strings and used a : to separate the encodings. : is not possible in a base 64 encoding so it is a safe delimiter. import java.util.*; public class Program { public static void main(String[] args) { String a="hello"; String b="world"; a=Base64.getEncoder().encodeToString(a.getBytes()) + ":" + Base64.getEncoder().encodeToString(b.getBytes()); b = new String(Base64.getDecoder().decode(a.substring(0, a.indexOf(":")))); a = new String(Base64.getDecoder().decode(a.substring(a.indexOf(":") + 1))); System.out.println(a); System.out.println(b); } }
