How can I implement data encryption and decryption in my web application to protect sensitive information?
To implement data encryption and decryption in a web application, you can follow these steps: 1. Choose a strong encryption algorithm such as AES. 2. Generate a secure encryption key. 3. Encrypt the sensitive data using the encryption key. 4. Store the encrypted data in your database or any other storage medium. 5. When retrieving the data, decrypt it using the encryption key. This ensures that even if the data gets compromised, it remains unreadable without the encryption key. It is also essential to use secure protocols such as HTTPS to prevent man-in-the-middle attacks.
