Have you participated in independently implementing an authentication system for a project?

Yes, I have implemented an authentication system from scratch in C#. The main steps included:

• Storing passwords in the database using hashing (e.g., BCrypt).
• Implementing registration and login mechanisms with data verification.
• Using JWT (JSON Web Tokens) for session management and authorization.
• Ensuring protection against common vulnerabilities such as SQL injection and brute-force attacks.

Example of simple password hashing using BCrypt:

using BCrypt.Net;

string password = "user_password";
string hashedPassword = BCrypt.Net.BCrypt.HashPassword(password);

// Password verification
bool isValid = BCrypt.Net.BCrypt.Verify("user_password", hashedPassword);
