如何利用java自带的base64实现加密、解密程序源码:
import java.io.UnsupportedEncodingException;
import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;
public class TestBase64 {
// 加密
public static String getBase64(String str) {
byte[] b = null;
String s = null;
try {
b = str.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
if (b != null) {
s = new BASE64Encoder().encode(b);
}
return s;
}
// 解密
public static String getFromBase64(String s) {
byte[] b = null;
String result = null;
if (s != null) {
BASE64Decoder decoder = new BASE64Decoder();
try {
b = decoder.decodeBuffer(s);
result = new String(b, "utf-8");
} catch (Exception e) {
e.printStackTrace();
}
}
return result;
}
//测试
public static void main(String[] args) {
String str="www.itxm.net";
System.out.println(getBase64(str));
System.out.println(getFromBase64(getBase64(str)));
}
}
