AES加解密JAVA实现（源码）

最近写一些加密解密的代码，找了不少的文章，结合自己的理解，现把我写的代码POST出来，供大家参考。import javax.crypto.*;import javax.crypto.spec.*;public class AES { public static void main(String[] args) throws Exception { /* 加密用的Key 可以用26个字母和数字组成，最好不要用保留字符，虽然不会错，至于怎么裁决，个人看情况而定 */ String cKey = "1234567890abcDEF"; //需要加密的字串 String cSrc = "我的MSN：xxxx@hotmail.com，QQ：10000" ; //加密 long lStart = System.currentTimeMillis(); String enString = AES.Encrypt(cSrc, cKey); System.out.println("加密后的字串是：" + enString); long lUseTime = System.currentTimeMillis() - lStart; System.out.println("加密耗时：" + lUseTime + "毫秒"); //解密 lStart = System.currentTimeMillis(); String DeString = AES.Decrypt(enString, cKey); System.out.println("解密后的字串是：" + DeString); lUseTime = System.currentTimeMillis() - lStart; System.out.println("解密耗时：" + lUseTime + "毫秒"); } public static String Decrypt(String sSrc, String sKey) throws Exception { try { //判断Key是否正确 if (sKey == null) { System.out.print("Key为空null"); return null; } //判断Key是否为16位 if (sKey.length() != 16) { System.out.print("Key长度不是16位"); return null; } byte[] raw = sKey.getBytes("ASCII"); SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.DECRYPT_MODE, skeySpec); byte[] encrypted1 = hex2byte(sSrc); try { byte[] original = cipher.doFinal(encrypted1); String originalString = new String(original); return originalString; } catch (Excep
