javax.crypto.BadPaddingException: Given final block not properly padded
1.javax.crypto.BadPaddingException: Given final block not properly padded

异常如下

1）要确认下是否加密和解密都是使用相同的填充算法（也就是说，是否都是使用PKCS5Padding）
2）确认下你要解密的字节数组是否正确。

javax.crypto.IllegalBlockSizeException:

Input length must be multiple of 8 when decrypting with padded cipher

输入长度必须是8的倍数时，解密密文
