What is encryption and how does it enhance security?

Encryption is the process of converting information into a code to prevent unauthorized access. It enhances security by ensuring that only authorized users can read the data.

Can you explain the different types of encryption?

Sure! The main types of encryption are symmetric encryption, where the same key is used for both encryption and decryption, and asymmetric encryption, which uses a pair of keys (public and private) for secure communication.

How does encryption protect data in transit?

Encryption protects data in transit by encoding the information as it travels over networks, making it unreadable to anyone who intercepts it.

What are some common encryption algorithms?

Common encryption algorithms include AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and DES (Data Encryption Standard). Each has its own strengths and use cases.

Is encryption foolproof?

While encryption significantly enhances security, it's not foolproof. Vulnerabilities can exist in implementation, and strong passwords and security practices are also essential.
