JAVA 使用BASE64加密、解密

import sun.misc.BASE64Decoder;（此Jar位於rt.jar）

/** * 用BASE64加密 * @param str * @return */private static String getBASE64(String str) {byte[] b = str.getBytes();String s = null;if (b != null) {s = new sun.misc.BASE64Encoder().encode(b);}return s;}/** * 解密BASE64字竄 * @param s * @return */private static String getFromBASE64(String s) {byte[] b = null;if (s != null) {BASE64Decoder decoder = new BASE64Decoder();try {b = decoder.decodeBuffer(s);return new String(b);} catch (Exception e) {e.printStackTrace();}}return new String(b);}
