Securing Sensitive Information
When interacting with databases, it’s crucial to handle sensitive information securely. This includes encrypting passwords and limiting exposure to sensitive data.
// Hashing passwords before storing them
const bcrypt = require('bcrypt');
const saltRounds = 10;
async function hashPassword(password) {
return await bcrypt.hash(password, saltRounds);
}
// Example: POST /users
app.post('/users', authenticateToken, authorize('admin'), validateData, async (req, res) => {
try {
const { username, email, password } = req.body;
const hashedPassword = await hashPassword(password);
const query = `INSERT INTO users (username, email, password) VALUES ('${username}', '${email}', '${hashedPassword}')`;
await executeQuery(query);
res.status(201).json({ message: 'User created successfully' });
} catch (err) {
res.status(500).json({ message: 'Internal server error' });
}
});
Build a Secure SQL Server REST API
In today’s digital landscape, the demand for secure and efficient data access is paramount. One common approach to achieving this is through the implementation of a REST API, which allows for seamless communication between client applications and databases.
In this article, we will delve into the process of building a secure SQL Server REST API, covering essential concepts and providing detailed examples along the way.
