自己写了个java的，但是加密出来，前面一段相同，后面一段不同
public static String encrypt(String input, String key) throws Exception {
byte[] crypted = null;
try {
SecretKeySpec skey = new SecretKeySpec(key.getBytes(), "AES");
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
cipher.init(Cipher.ENCRYPT_MODE, skey);
crypted = cipher.doFinal(input.getBytes());
} catch (Exception e) {
System.out.println(e.toString());
}
return new String(byte2hex(crypted));
}
