c加密算法，比较实用的一程序，在别人那拷的.

该程序实现单层的DES加密算法，其中CDes.cpp为源程序，其中调用的文件功能如下：dataofText.txt文件是输入的明文，以换行分割各个数据；dataofKey.txt文件时输入的密钥，以换行分割；dataofDES.txt文件是输出的加密数据，其中包括各轮子密钥以及各轮加密输出，以及最后得到的密文，在文件中都有说明。-the realization of the single DES encryption algorithm, which CDes.cpp to source files, Calling the document which functions as follows : dataofText.txt document is imported specifically, in exchange for various bits of data; dataofKey.txt paper input key to change bits; dataofDES.txt document is the output data encryption, including the wheels round and the key encryption exports, and finally the secret text in the document have been described.

标准的数据加密算法-standard data encryption algorithm

此为国外转载函数，可将任意字符转换为md5 16为字符加密形式，而且为不可逆转换。-reproduced here for foreign functions, arbitrary characters can be converted to 16 md5 encrypted form of characters, but also to irreversible change.

带密钥的md5算法库md5lib.h共有下列函数： char* MDString (char *) /*输入任意一个字符串，经过md5算法处理后，返回结果：一个定长（32个字符） 字符串 */ char* MDFile (char *) /*输入任意一个文件名，文件内容经过md5算法处理后，返回结果：一个定长 （32个字符）字符串 */ char* hmac_md5(char* text, char* key) /*输入任意一个字符串text,和一个用做密钥的字符串key,经过hmac_md5算法处 理，返回处理结果：一个定长字符串（32个字符）*/ 具体使用方法可参考例子sample.c,其运行结果在本文后面。-Md5 algorithm with a key repository md5lib.h total of the following functions: char* MDString (char*) /* enter any one string, after md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* MDFile (char*) /* enter any of the file name, file contents through the md5 algorithm processing, return the result: a fixed-length (32 characters) string*/char* hmac_md5 (char* text, char* key) /* input a string of arbitrary text, and a string key used as key, after hmac_md5 algorithm processing, return processing results: a fixed-length string (32 characters)*/specific examples of the use of methods can be found sample.c, the results

椭圆曲线密码C实现的，可以在++6.0下编译通过。希望对大家有帮助！-Elliptic Curve Cryptography C achieved in++ 6.0 compiler passed under. Would like to help everyone!

个人编的rsa的源代码，算出public―private key；其中有Euclid，Extend Euclid的实现，以及Millar-Rabin test的实现，和加密/解密-Rsa personal series of source code, calculate the public-private key including Euclid, Extend Euclid realization, as well as the Millar-Rabin test realization, and the encryption/decryption
