現象描述：

windows

上加解密正常，

linux

上加密正常，解密時發生如下異常

：

javax.crypto.BadPaddingException:

Given final block not properly

解決後代碼如下：

KeyGenerator keyGen = KeyGenerator.getInstance("AES");

String pwd ="passordgggggg";

SecureRandom random=SecureRandom.getInstance("SHA1

//需要自己手動設定，在liunx下需要手動指定隨機型別，否則每次生成會不一樣的密碼，解密是也是需要這步

random.setSeed(pwd.getBytes());

keyGen.init(128, random);

SecretKey skey = keyGen.generateKey();

byte[] raw = skey.getEncoded();

SecretKeySpec skeySpec =new SecretKeySpec(raw,"AES");
