重庆大学，信息安全导论课程第二次作业。利用C++/Qt，根据S-AES算法编写和调试程序，提供GUI解密支持用户交互。提供普通单次加密、双重加密，以及三重加密的三种加密模式给用户进行使用，同时还实现了中间相遇攻击和CBC模式下的S-AES加密。

Simplified AES

A simplified version of AES-128 is implemented in C++ where padding is ommitted due to the assumption undertaken that the message will be exactly of 128-bit. A further simplified version of AES, known as S-AES, is also implemented.
