一个简单的文件加密器-a simple file encryption device

素数Robin―Millor测试法的C语言源码-Robin-Millor prime test of the C language source

个人觉得很不错的简单代码，用很少的程序实现，非常值得一看-in my view, it s a nice and simple code with a few program to achieve the aim. worth to take a look

将小于32位的码字用1011编程循环冗余码！ 并且可以检验已编好的循环冗余码是否正确！-Will be less than 32-bit code word to use Cyclic Redundancy Code 1011 programming! And can be tested has been a good cyclic redundancy code is correct!

多数程序设计语言处理整数的能力是有限的，如C语言中，int类型数据范围是-32767----32767。实际问题的处理过程中往往涉及大整数的运算，如RSA加密算法要求至少64bit的整数，本程序是设计算法实现大整数的加减运算。-majority programming language processing is integral to the limited capacity, such as C language, int data type is the scope-32767---- 32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, the procedure is designed algorithm large integer addition and subtraction operations.

测试对字符串的MD4。运行环境：vs2008 （注意选择“多字符”编译）-Testing of the string MD4. Operating environment: vs2008 (attention to the selection " multi-character" compilation)

MD5算法器，是一个非常实用简单的MD5算法器，用来加密，在公司用的很多，上次一同事向我要-MD5 algorithm, and is a very useful device simple MD5 algorithm for encryption, the company used many of my colleagues told me the last one to

这是密码学的一个常用算法TWOFISH128，对于学习密码学很有帮助啊。-This is a cryptographic algorithm used TWOFISH128, learning cryptography helpful ah.

MD5生成器，可以生成字符串或文件的MD5值-MD5 Generator can generate the MD5 string or document the value of
