利用java自带的base64实现加密、解密

package com.stone.util; import java.io.UnsupportedEncodingException; import sun.misc.*; public class Base64 { // 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; } }
