一个DES加密算法的实现

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

一个用ATL开发的Base64编码控件，使用简单,用EnCode64(str)编码,EnCode64(str)解码,属性EnCode存放源码,属性DeCode存放Base64码，开发平台：VC.Net- The Base64 code which develops with ATL controls, the use is simple, (str) codes with EnCode64, EnCode64 (str) decodes, the attribute EnCode depositing source code, attribute DeCode deposits the Base64 code, develops the platform: VC.Net

个人整理的CRC的一些简单基本资料,里面还附带CRC的算法实现(C语言),对新手来说,是一份不错的资料-Personal order of CRC s some simple basic information, which also comes with CRC s algorithm (C language), on the novice, is a good information

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
