DES

壳代码，对于学习壳编写的同学具有一定的参考价值，绝对经典(Shell code, written for students to learn the shell has a certain reference value, an absolute classic)

一种加密算法,可以直接对密文进行操作，而不需要知道相应的明文。(homomorphic encryption)

检测CRC编码 看CRC编码在传输后是否有错误 有变动 (Detection CRC codes to see whether the CRC coding errors in the transmission there is a change)

修改本程序中的U盘的序列号后，程序可以变成你自己的独立的Ｕ盘启动密匙，　只能你的Ｕ盘才能打开程序　不需要往Ｕ盘中存入任何文件，就可实现用Ｕ盘加密程序.只能通过你的U盘启动你的程序 程序中有详细的注释(Encrypt your program by a soul U-disk without saving anything in you disk Modify the program, U-disk serial number, the program can become your own independent U disk key, only you can open U disk U disk does not need to deposit any file, can be achieved U disk encryption program)

AES加解密C语言源代码，可直接运行通过，方便大家借鉴学习(AES encryption and decryption of C language source code, can be directly run by, we facilitate learning from)

密码技术实验一经典密码学实验维多利亚密码加密解密(Password technological experiments classic cryptography experimental Victoria password encryption and decryption)

加密文件夹,十分好用 使用visual basic环境编程(lock file)

RSA-MFC,基于MFC的RSA加密算法的实现，可以用于16进制文件的加解密(RSA-MFC, the MFC based on the realization of RSA encryption algorithm, can be used for 16-band file encryption and decryption)

以DES加密算法为例理解对称密码算法，用计算机模拟DES加密解密算法。 (DES encryption algorithm as an example to understand the symmetric cipher algorithm, using computer simulation DES encryption and decryption algorithms.)

用于实现文本串的加密解密功能，程序自带密匙(Text string used to implement the encryption and decryption functions, comes with key program)
