这是一个用VC.net实现的AES的S

实现移位密码（扩展凯撒密码），用键盘接收明文和密钥，屏幕打印密文。-Achieve translocation password (Extension Caesar password), use the keyboard to receive explicit and key, screen printing ciphertext.

RSA算法的C++实现。公钥加密算法中使用最广的是RSA。RSA算法研制的最初理念与目标是努力使互联网安全可靠，旨在解决DES算法秘密密钥的利用公开信道传输分发的难题。-RSA algorithm is the C++ implementation. Public key encryption algorithm is the most widely used is RSA. RSA algorithm is developed by the original idea and objective is to make the Internet safe and reliable, aimed at resolving the DES algorithm is a secret key transmitted using the open channel distribution problems.

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

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）-a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1)

delphi6写的CRC32的加密算法。 另有付加例子程序-Delphi6 CRC wrote the encryption algorithm. Another example of pay increase procedures

这个是数据加密标准的VC算法-This is a standard data encrypt algorithm of VC

已经通过AES认证的AES的DELPHI实现，比较好，大家自己试试看，搜的-AES has been certified by the AES DELPHI, the better, we all give it a try and found the
