What is cryptography and how does it enhance security?

Cryptography is the practice of securing information by transforming it into an unreadable format. It enhances security by ensuring that only authorized parties can access and understand the data.

Can you explain the different types of cryptography?

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

What are some real-world applications of cryptography?

Cryptography is used in various applications, including secure online transactions, email encryption, VPNs, and securing sensitive data in storage.

How does cryptography protect data during transmission?

It protects data during transmission by encrypting the information before it is sent over the network, ensuring that even if intercepted, it remains unreadable without the decryption key.
