This project involves building a comprehensive file encryption tool that allows users to securely encrypt and decrypt files, ensuring data privacy and protection. The platform aims to provide an intuitive user experience for both individuals and organizations to manage sensitive information effectively.
The project aims to develop a scalable and efficient API that enables users to encrypt files, manage their encryption keys, and access encryption analytics. This API will support various front-end applications, including web and mobile interfaces.
In today's data-driven world, protecting sensitive information is paramount. This project will create an API that empowers users to secure their files easily and allows administrators to manage user access and system performance. Here’s a detailed look at how users will interact with the platform:
User Registration and Authentication
Sign Up: New users can create an account by providing a username, email, and password. Once registered, they will receive a confirmation email to verify their account.
Login: Registered users can log in using their email and password. For enhanced security, the API will support multi-factor authentication (MFA).
File Encryption and Decryption
Encrypt File: Users can upload a file and select an encryption method to secure it.
Decrypt File: Users can upload an encrypted file and provide the correct key or password
to decrypt it.Key Management: Users can generate, view, and manage their encryption keys securely
File Management
View Encrypted Files: Users can view a list of their encrypted files along with details such as encryption method and date of encryption.
Delete Encrypted Files: Users can delete their encrypted files from the system.
Analytics and Reporting
Encryption Usage Statistics: Users can access metrics on file encryption, including the number of files encrypted and the types of encryption methods used.
Download Reports: Users can download reports of their encryption activity for record-keeping.
Administrator Features
User Management: Administrators can manage user accounts, including resetting passwords and handling user queries.
System Monitoring: Administrators can monitor system performance and usage statistics to ensure optimal functionality.
Objectives
Allow users to sign up, log in, and manage their accounts.
Enable users to encrypt and decrypt files securely.
Provide analytics for encryption activities to track usage and performance.
Enable administrators to manage users and monitor system performance effectively.
Functional Requirements
User Management
Sign Up: Users can create an account with a username, email, and password.
Login: Users can log in using their credentials.
Profile Management: Users can update their profile information.
File Encryption and Decryption
POST /encrypt: Users can upload a file to be encrypted.
POST /decrypt: Users can upload an encrypted file to be decrypted.
POST /keys: Users can manage their encryption keys.
File Management
GET /files: Users can retrieve a list of their encrypted files.
DELETE /files/{id}: Users can delete an encrypted file. Analytics and Reporting
GET /analytics: Users can view encryption usage statistics.
GET /reports: Users can download their encryption activity reports.
Non-Functional Requirements
Scalability: The API should handle a growing number of users and file encryption requests.
Performance: The API should have a fast response time and handle concurrent requests efficiently.
Security: Implement authentication and authorization mechanisms to protect user data.
Reliability: The API should be highly available and handle failures gracefully.
Usability: The API should be easy to use and well-documented.
Use Cases
User Sign Up and Login: New users sign up, and existing users log in.
Encrypt and Decrypt Files: Users encrypt and decrypt files securely.
Manage Encrypted Files: Users manage their list of encrypted files.
View Encryption Analytics: Users check their encryption activity metrics.
