用MATLAB编写的混沌序列图像加密程序，密钥可以从0到1之间的任何一个数，加密密钥跟解密密钥一样才能正确解密。-MATLAB prepared by the chaotic sequence image encryption procedures, Key from 0-1 between any one of the few, encryption, decryption keys with the same key can decrypt correctly.

DES算法的加解密程序，MATLAB实现，还有实验报告一并附上。-DES algorithm encryption and decryption procedures, MATLAB implementation, the key length can only be eight.
