实现RC4流密码算法，对文件进行加密，并将加密的内容以文件形式输出，控制台调用。(Achieve RC4 stream cipher algorithm, to encrypt files and encrypt the contents of the output file format, called the console.)

AES加密

一个Data Encryption Standard加密程序(DES encryption)

加权融合算法，对不同的因素加不同的权值以达到最优(weighted fusion algorithm, the different factors in different weights to achieve optimal)

CRC-16和CRC-CCITT的C程序实现，非常适用。(CRC-16 and CRC-CCITT program。)

说明：  openssh的rpm源代码 openssh是一款优秀的加密的文件传输工具 优于ftp(openssh rpm openssh source code is a good encrypted file transfer tool than ftp)

ASIC design and synthesis

凯撒密码作为一种最为古老的对称加密体制，在古罗马的时候都已经很流行，他的基本思想是：通过把字母移动一定的位数来实现加密和解密。例如，如果密匙是把明文字母的位数向后移动三位，那么明文字母B就变成了密文的E，依次类推，X将变成A，Y变成B，Z变成C，由此可见，位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys.
