Abstract
Do research about the application area of RSA encryption and reason that RSA can be used for file encryption. Design a RSA file-encrypt solution and complete an application on Microsoft Windows. Design a C++ class based on normal RSA algorithm. And make a DLL module based on the class. Then complete a .Net Framework window-application using that DLL. The application can encrypt any file and decrypt them. The file after encryption can be saved as a text file. And the encryption-keys also can be saved as text.Provide pivotal classes chart, project description, core algorithm flowchart, all source code, and module interfaces document. Do application performance test and record the performance data. Analyze the result then optimize core algorithm and improve the application. Finally, create a practical application using RSA algorithm that can encrypt and decrypt any file. And several modules in the project can be reuse by other applications. For instance, the C++ class can be cross-compiled for handheld devices, the DLL can be referenced by other win32 applications, and the .Net class can be easily referenced by web server applications or web services.
