128位(或192或256bit该代码以128为例)的密钥长度和分组长度，数据分组（输入的明文），先进行逐比特异或（AddRoundKey） 运算。然后通过循环十次非线性代换（SubBytes）、行变换（ShiftRows）、列变换（MixColumns）、逐比特异或【最后一轮不进行列变换】 的过程，输出128位（或192或256bit）数据即是密文。这就是加密过程。之后进行之前的逆过程，即可得到明文，此为解密过程。

极好的加密程序，DES的接班人，源码是DEHLPHI的Pascal，编译后可直接运行-Excellent encryption, DES s successor, is DEHLPHI source of Pascal, the compiler can be run directly

e-maill文件加密程序完整的源代码，使用LeapFrog2加密方法.zip-e-maill document encryption procedure integrity source code, uses the LeapFrog2 encryption zip

MD5加密算法源代码,个人感觉相当有学习的热的价值,希望大家共同学习,共同进步.-MD5 encryption algorithm source code, personal feeling quite hot the value of learning, I hope everyone learn together and seek common progress.

RSA的小程序，源码产生随机素数调用方法：N.GetPrime(bits)返回值：N被赋值为一个bits位（0x100000000进制长度）的素数-RSA small program source random-number call methods : N. GetPrime (bits) Returns : N has been assigned a bits- (0x100000000 band length) of prime numbers

使用的是简单的字节加减，允许输入中文本源代码不适合加密任何重要文档仅供交流使用使用Visual Studio 2015 制作

这两个工程主要用CSP 1、CSPTEST 写的比较乱 主要是给当时一个朋友做参考调用的 完成非对称密钥的生成、导入、导出、加密、解密、对称的加密解密、签名、验证。 2、CSTTEST2 写的比前个好些，但是平时上班，下班自己也要写论文，所以花的时间也不太多，很多地方都偷懒了。比如文件大小我没有用NEW 而且指定了1024 有需要的朋友可以自己修改。这个工程主要是非对称的密钥的导出和导入，还有就是会话密钥的操作。-these two works mainly with a CSP. CSPTEST comparison was made mainly to the chaos when a friend called to refer to the completion of the non-symmetric key generation, importing and exporting, encryption, decryption, symmetric encryption and decryption, signature, the certification. 2, CSTTEST2 write better than in the previous months, but usually go to work and finish their own toilet paper so I spent the time is not too much, all of the lazy. For instance, file size I have not used the NEW 1024 and designated a need to amend their friends. The project mainly non-symmetric keys to the Export and Import, there is the session key operation.
