在win下正常運行但在linux下報錯Given final block not properly padded. Such issues can arise if a bad key 好像是因為win中生成的key是一樣的，而在部分linux下會變成隨機

一下是解密修改前後的對照

 1     public static byte[] decrypt(byte[] content) {
 2         String password="123456";
 3         try {
 4             KeyGenerator kgen = KeyGenerator.getInstance("AES");//
 
 創建AES的Key生產者
 5             //防止linux下 隨機生成key 
 6             SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
 7             random.setSeed(password.getBytes("UTF-8"));
 8             kgen.init(128, random);
 9             //kgen.init(128, new SecureRandom(password.getBytes()));
10             SecretKey secretKey = kgen.generateKey();//
 
 根據用戶密碼，生成一個密鑰
11             byte[] enCodeFormat = secretKey.getEncoded();// 返回基本編碼格式的密鑰
12             SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");// 轉換為AES專用密鑰
13             Cipher cipher = Cipher.getInstance("AES");// 創建密碼器
14             cipher.init(Cipher.DECRYPT_MODE, key);// 初始化為解密模式的密碼器
 

15             byte[] result = cipher.doFinal(content);  
16             return result; // 明文   
17 
18         } catch (NoSuchAlgorithmException e) {
19             e.printStackTrace();
20         } catch (NoSuchPaddingException e) {
21             e.printStackTrace();
22         } catch (InvalidKeyException e) {
23             e.printStackTrace();
24         } catch (IllegalBlockSizeException e) {
25             e.printStackTrace();
26         } catch (BadPaddingException e) {
27             e.printStackTrace();
28         } catch (UnsupportedEncodingException e) {
29             // TODO Auto-generated catch block
30             e.printStackTrace();
31         }
32         return null;
33     }

下面是修改過的

 1     public static byte[] decrypt(byte[] content) {
 2         String password="123456";
 3         try {
 4             KeyGenerator kgen = KeyGenerator.getInstance("AES");// 創建AES的Key生產者
 5             //防止linux下 隨機生成key 
 6             SecureRandom random = SecureRandom.getInstance("SHA1PRNG");
 7             random.setSeed(password.getBytes("UTF-8"));
 8             kgen.init(128, random);
 9             //kgen.init(128, new SecureRandom(password.getBytes()));
10             SecretKey secretKey = kgen.generateKey();// 根據用戶密碼，生成一個密鑰
11             byte[] enCodeFormat = secretKey.getEncoded();// 返回基本編碼格式的密鑰
12             SecretKeySpec key = new SecretKeySpec(enCodeFormat, "AES");// 轉換為AES專用密鑰
13             Cipher cipher = Cipher.getInstance("AES");// 創建密碼器
14             cipher.init(Cipher.DECRYPT_MODE, key);// 初始化為解密模式的密碼器
15             byte[] result = cipher.doFinal(content);  
16             return result; // 明文   
17 
18         } catch (NoSuchAlgorithmException e) {
19             e.printStackTrace();
20         } catch (NoSuchPaddingException e) {
21             e.printStackTrace();
22         } catch (InvalidKeyException e) {
23             e.printStackTrace();
24         } catch (IllegalBlockSizeException e) {
25             e.printStackTrace();
26         } catch (BadPaddingException e) {
27             e.printStackTrace();
28         } catch (UnsupportedEncodingException e) {
29             // TODO Auto-generated catch block
30             e.printStackTrace();
31         }
32         return null;
33     }
