最近项目中会用到加密、解密。所以把项目中原来的加解密实现整理一下。
这里附一篇链接，把AES加密算法解释的非常透彻的男人，膜拜一下。https://blog.csdn.net/qq_28205153/article/details/55798628。对于加密算法的理解非常肤浅，分类上只知道对称、非对称加密，而且还不知道到底有什么区别。以前用过的也就MD5吧，真的小白一枚。
上面的链接很详细，就不班门弄斧了。直接上实现。仅供学习，如果涉及版权问题，请联系我。

//Rijndael (pronounced Reindaal) is a block cipher, designed by Joan Daemen and Vincent Rijmen as a candidate algorithm for the AES.
//The cipher has a variable block length and key length. The authors currently specify how to use keys with a length
//of 128, 192, or 256 bits to encrypt blocks with al length of 128, 192 or 256 bits (all nine combinations of
//key length and block length are possible). Both block length and key length can be extended very easily to
// multiples of 32 bits.
//Rijndael can be implemented very efficiently on a wide range of processors and in hardware.
//This implementation is based on the Java Implementation used with the Cryptix toolkit found at:
//http://www.esat.kuleuven.ac.be/~rijmen/rijndael/rijndael.zip
//Java code authors: Raif S. Naffah, Paulo S. L. M. Barreto
//This Implementation was tested against KAT test published by the authors of the method and the
//results were identical.

//The Electronic Code Book (ECB), Cipher Block Chaining (CBC) and Cipher Feedback Block (CFB) modes
//are implemented.
//In ECB mode if the same block is encrypted twice with the same key, the resulting
//ciphertext blocks are the same.
//In CBC Mode a ciphertext block is obtained by first xoring the
//plaintext block with the previous ciphertext block, and encrypting the resulting value.
//In CFB mode a ciphertext block is obtained by encrypting the previous ciphertext block
//and xoring the resulting value with the plaintext.

封装一下加密，解密的方法，只要传入明文或者密文，进行加解密就可以了
//数据加密

}其中的几个宏是约定的秘钥
#define CYPHER_KEY "约定的秘钥或者可以通过非对称加密传输!"
#define CYPHER_CHAIN "@约定的秘钥或者可以通过非对称加密传输"
#define KEY_LEN 16
#define BLOCK_LEN 16
#define ARR_LEN 50
服务端接口是通过C#实现的。对应的加解密封装如下
