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.

此为Keeloq算法的解密C代码，keeloq最常用于无线门锁装置。(KeeLoq is a proprietary hardware-dedicated NLFSR-based block cipher. The uni-directional command transfer protocol was designed by Frederick Bruwer, PhD, CEO at Nanoteq (Pty) Ltd)

用C/C++实现加解密算法及其应用：DES（或AES）和基于DES（或AES）的CMAC。(With C/C++ achieve encryption and decryption algorithm and its application: DES (or AES) and based on DES (or AES) of CMAC.)

将天骄2服务端的加密文本文件与生成的软件放在同一目录下,点击批量转换, 完成后会在同目录下生成一个名为temp的文件夹,其中存放的就是转换后的文件. 因为加密和解密的规则完全相同,所以加密过程和解密过程相同, 也就是说如果原来的文件存放的是原文,转换后就会生成密文,如果原来是密文,转换后生成原文. 适用于天骄2,凤舞天骄的所有版本服务端.(The the Tianjiao 2 server encrypted text file in the same directory with the generated software, click on the batch conversion finished, it will generate a folder named temp in the same directory, which store the converted file encryption and decryption rules are identical, so the encryption and decryption process is the same, that is to say if the original file is stored in the original conversion will generate the ciphertext, if the original ciphertext, conversion generated text. apply to tianjiao, all of Fung Mo tianjiao, the version of the server.)

文件加密器,实现对文件加密,用来学习的代码(File encryption, encrypting files, the code used to study)

采用c++实现RC4加密解密算法，该代码可以加密解密任意格式的文件( U91C7 u758ccc_cn R U6587 u4EF6)

信息安全的RSA与DES加解密算法的实现，用的是Visual C++MFC(Information Security RSA encryption and decryption with the DES algorithm, using the Visual C++ MFC)
