base64加密解密

Java代码

1. String s = "HELLO WORLD！";
2. BASE64Encoder encoder = new BASE64Encoder();
3. // BASE64加密
4. System.out.println(encoder.encode(s.getBytes()));
5. String encode = encoder.encode(s.getBytes());
6. BASE64Decoder decoder = new BASE64Decoder();
7. // BASE64解密
8. System.out.println(new String(decoder.decodeBuffer(encode)));
