OpenSSL的RSA算法应用举例。是用VC写的，有实用价值。

MD5加密单元及DEMO-MD5 encryption modules and DEMO

File Encryption Utility（使用Blowfish算法给文件加密的完整程序）VC 源代码-File Encryption Utility (using Blowfish encryption algorithm to document the integrity of procedures) VC source code

RSA加密实现，希望对大家有所帮助，研究算法是很让人痛苦的事情，大家多多努力-RSA encryption realize, I hope to be helpful to everyone to study the algorithm is a very painful thing, a lot of U.S. efforts

硬件求解平方根源代码加密 (硬件求解平方根的，将license添加到原有的MaxplusII或QuartusII的license中就可以直接使用，但源代码加密。altera提供 )-solving square root of the hardware encryption code (square root of the hardware solution will be added to the original license MaxplusII or Quartus II of the license which can be directly used, but the source code encryption. ALTERA provide)

算术运算实现字母的替换。凯撒加密就是一种单字母替换法：通过用户给出密钥将字母加上密码变成密文-Arithmetic operations to achieve the replacement of letters. Caesar encryption is the replacement of a single-letter law: the user is given the letter key will be encrypted into a ciphertext

Vigenere 体制 本程序使用dev c++开发实现，希望对大家有用.-Vigenere institutional procedures for the use of the dev c achieve development, we hope that the right useful.

除了上面提到的压缩方法，你也可以调用VB的工具MakeCab.exe（在VB5setupkitkitfil32或VB98WizardsPDWizard目录下）生成.cab文件。先构造一个Directive 文件(*.ddf)，然后使用Shell命令调用MakeCAB /f excel.ddf就可以生成*.cab文件。关于Directive 文件的格式，可以参考MSDN Library中的《MakeCAB: A Compression and Disk Layout Tool》一文。 -addition to the above-mentioned methods of compression, you can call VB Tools MakeCab.exe (VB5 setupkit kitfil32 or VB98 Wizards PDWizard directory) production. Cab document. First constructed a Directive document (*. DDF), then use the Shell order call MakeCAB/f excel.ddf can generate*. cab documents. Directive on the document format, they can refer to the MSDN Library "MakeCAB : A Disk Compression and Layout Tool," a text.

MD5算法的ASP实现． 它在MD4的基础上增加了"安全-带子"（Safety-Belts）的概念。虽然MD5比MD4稍微慢一些，但却更为安全。MD5也为一种非常优秀的中间技术。-MD5 algorithm ASP. It MD4 increase on the basis of "safety-belt" (Safety-Belts) concept. Although MD5 than MD4 slightly slower, but more secure. MD5 also as a very good intermediate technology.

可列出系统MY CA ROOT USERDS等存储区的证书，代码参考msdn-system can be shown MY CA ROOT USERDS storage of certificates, reference code VARIANT
