加密与解码――密码技术剖析与实战应用中的一个例子

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

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x264编码的可执行程序 x264.exe，因为我只修改了 x264 的算法，未加入任何汇编，也没有修改x264的接口和功能，所以原版 x264 能运行的平台，此程序也应当能运行，且功能及调用方式不变。 执行命令方式为： -o 输出文件 输入文件 宽x高 -B 目标码率-X264 encoding an executable program x264.exe, because I only modified x264 algorithms, not to join any compilation, there is no modification of the interface and functionality of x264, the x264 can run the original platform, this procedure should also be able to run, and function and calls the same way. For the implementation of the order:-o output file input file width x high-B target rate

简单的RSA加密范例-simple example of the RSA encryption

转CRC16的小程序,很好用呀,大家试一试-CRC16 turn a small program, very good with the ah, we try

这是RC5算法的ASM实现，效率很高，可以直接用到工程中去-This is the RC5 algorithm ASM realization of very efficient and can be used directly on projects to

C语言环境下的AES加密算法，支持128位的AES加密。-C language environment AES encryption algorithm, support 128-bit AES encryption.
