2.加密与解密源码:
/*
 * 解密
 */
public static String desEncrypt(String data) throws Exception
{
String key = "1938567890CRHRTF";
byte[] encrypted1 = Base64.decode(data.getBytes(), Base64.DEFAULT);
//byte[] encrypted1 = Base64.decode(data);
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
cipher.init(Cipher.DECRYPT_MODE, keyspec);
byte[] original = cipher.doFinal(encrypted1);
return new String(original, "UTF-8"); } /**
 * 加密
 */
public static String encrypt(String data) throws Exception
{
String key = "1938567890CRHRTF";
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
//Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");
cipher.init(Cipher.ENCRYPT_MODE, keyspec);
byte[] encrypted = cipher.doFinal(data.getBytes());
return Base64.encodeToString(encrypted, Base64.DEFAULT); }
3.现象进一步描述:
加密与解密的代码:在安卓移动端测试时,没有问题,在后端测试也没有问题.可是一旦加密放在前端,解密放在后端就报如上表述的错误.请问大家这是什么情况.
