How does data encryption work in web applications?

Data encryption in web applications involves converting data into a coded format to prevent unauthorized access. This ensures that sensitive information, like user credentials and personal data, is protected during transmission and storage.

What are the common encryption methods used?

Common encryption methods include AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and TLS (Transport Layer Security) for securing data in transit.

How can I implement encryption in my web app?

You can implement encryption by using libraries like OpenSSL for backend encryption and ensuring that your web app uses HTTPS to secure data in transit.

Are there any best practices for data encryption?

Yes, best practices include using strong encryption algorithms, regularly updating your encryption keys, and ensuring that sensitive data is encrypted both in transit and at rest.
