des加密算法具体实现，自己长期使用的，使用时引入即可

用C编写的100行DES加密算法，请参考-C prepared with 100 lines DES encryption algorithm, please refer to

AES算法的实现，大家可以参考一下看看。-AES algorithm, we can refer you to see.

计算文件hash值的源代码，包含crc,md2,md4,md5,sha,sha1,sha256,ra-Calculated hash value of document

这个是高级加密标准的C语言程序-this is the Advanced Encryption Standard C Programming Language

按照分组密码运行的CBC方式，将其中的DES算法置换为S-DES，分组长度为8BIT，初始矢量V1分别设置为00H,FFH,及任意8BIT无符号整数，实现该加密/解密模型-running CBC, which will be the replacement for the DES algorithm S-DES, a length of 8BIT initial vector V1 were set to 00H, FFH, and the arbitrary 8BIT unsigned integers, the achievement of this encryption/decryption model

IBM的MARS加密算法-IBMMARS

MD5算法的实现。MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。 -MD5 algorithm. MD5 to 512 groups to deal with the importation of information and each group was also divided into 16 groups of 32 seats, After a series of processing, the output from the algorithm 4 32 subgroups, 4 32 this group will generate a cascade 128 hash value.
