base64加密解密

 

String s = "HELLO WORLD！";
BASE64Encoder encoder = new BASE64Encoder();
// BASE64加密
System.out.println(encoder.encode(s.getBytes()));
String encode = encoder.encode(s.getBytes());
BASE64Decoder decoder = new BASE64Decoder();
// BASE64解密
System.out.println(new String(decoder.decodeBuffer(encode)));
