今天我们学习了des对称加密算法这是一个des算法的C++实现(This is a des !)

21加密算法,用vB语言编写实现,可了解各种加密算法的结构(21, encryption algorithm, and realize vB languages, can understand the structure of a variety of encryption algorithms)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

使用MD5算法对数据和文件进行加密，信息安全(Using the MD5 algorithm to encrypt the data and documents, information security)

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.

VB文件加密器（异或加密）,有需要的就下载吧。(VB file encryption (XOR encryption), there is a need to download it.)

PF140.514版digsilent软件的两个破解文件，按一定操作步骤即可免狗驱动，本人已在XP环境下使用，没有问题。希望对采用该软件的人有一点帮助！(Two crack file PF140.514 the version digsilent software, Free Dog certain steps to drive, I have XP environment, there is no problem. I hope the software a little help!)

VMp——一款可以超强保护文件防止破解的加壳工具，软件设计员的绝佳伴侣！ (VMp- a super-protected files can be packed to prevent cracking of the tools, software designers the perfect partner!)

说明：  混合加密系统，支持多种加密方式混合加密系统，支持多种加密方式(Hybrid encryption system)
