根据自己的加密要求可以修改，MD5加密处理单元。

MD5的全称是Message-digest Algorithm 5（信息-摘要算法），用于确保信息传输完整一致。本程序是c语言版的md5加密解密源码！-The full name of MD5 is Message-digest Algorithm 5 (Information- Summary of algorithm), to ensure the integrity of the information transmission line. This procedure is the c language version of the md5 encryption source code!

对于密码学感兴趣的读者适合，当然要求一定的基础-for cryptography for interested readers, of course, requires a certain basis

这是一个用VC.net实现的AES的S-box的实现代码，包括求逆和s盒的实现代码-This is a realization of the use VC.net AES S-box realization of the code, including inversion and the realization s box code

一篇09年很不错的关于密码学的论文，是从IEEE上下载的，内容很权威-A very good 2009 paper on cryptography and is downloaded from the IEEE, the content is authoritative

AES加密软件，用于加密当前文本框中的内容。使用的是美国国家标准（也被ISO所采纳）最新加密算法AES。-AES encryption software, encryption for the current contents of the text box. The use of the American National Standards (also adopted by the ISO) the latest encryption algorithm AES.

算术运算实现字母的替换。凯撒加密就是一种单字母替换法：通过用户给出密钥将字母加上密码变成密文-Arithmetic operations to achieve the replacement of letters. Caesar encryption is the replacement of a single-letter law: the user is given the letter key will be encrypted into a ciphertext
