- 4. OVERVIEW OF THE PROJECT • A E-commerce application, a web site where users can store their files (irrespective of type ) without horrifying by security threats. • Depending on the context, it’s been names as ‘safedrop.com’. • User facilities A fresh user must sign up to create an account One has to log in using account information to access the uploading and downloading(if any) facility There is a scope for resetting password if anyone forgets Once uploaded ,a file will be stored in encrypted version One can download only files uploaded by oneself in decrypted form There is also provision for changing password ,updating one’s profile picture and deleting account
- 5. OBJECTIVE • Making a file uploading and downloading site. • Assuring safety as much as possible. • Providing user the scope to store file irrespective of the file type. • To facilitate user to change password, update profile image and delete account.

- 33. TESTING Testing is an investigation conducted to provide stakeholders with information about the quality of the product or service under test. Software testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks at implementation of the software.

- 36. FUTURE SCOPE The interaction procedure of user and the web application can be further more improved to make it interactive and user friendly .The web page layout may be improved .we are trying to upgrade it into a file storage site as well as a file sharing site so that more users can be attracted .We think more flexibility and interactive features can make it more bigger.
- 37. CONCLUSION After developing the application we have got a clear idea on web development, especially in ms.net features, got a clear idea on how the encryption or decryption takes place. We have come to know the pros & cons of ms.net, the scopes of it and how it differs from other web development techniques. I hope, in future, the experience will help us in developing any web application and in career.
