This comprehensive guide covers the design, features, security architecture, and deployment steps for a GitHub-exclusive online voting system project. 📌 Core Features of the System

CREATE TABLE elections ( id INT AUTO_INCREMENT PRIMARY KEY, title VARCHAR(200), description TEXT, start_date DATETIME, end_date DATETIME, status ENUM('upcoming','active','ended') DEFAULT 'upcoming' ); // config

-- Table: votes CREATE TABLE votes ( id INT AUTO_INCREMENT PRIMARY KEY, user_id INT NOT NULL, candidate_id INT NOT NULL, position_id INT NOT NULL, voted_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, FOREIGN KEY (user_id) REFERENCES users(id), FOREIGN KEY (candidate_id) REFERENCES candidates(id) );

: Secure sign-up processes often enhanced by OTP (One Time Password) or unique ID generation to verify voter identity.

: Never store plain-text passwords. Use PHP's native password_hash($password, PASSWORD_ARGON2ID) or PASSWORD_BCRYPT algorithms during user registration and CSV imports. Critical Security Practices Implemented

: Store passwords using PASSWORD_ARGON2ID or PASSWORD_BCRYPT . Never store cleartext or MD5-hashed passwords.
