What is cryptography and why is it important?

Cryptography is the practice of securing information by transforming it into an unreadable format. It's crucial for protecting data.

Can you explain the different types of cryptography?

Sure! There are mainly two types: symmetric key cryptography, where the same key is used for encryption and decryption, and asymmetric key cryptography, which uses a pair of keys.

What are some real-world applications of cryptography?

Cryptography is used in various applications like securing online transactions, protecting sensitive data, and ensuring privacy in communications.

How does encryption work?

Encryption transforms readable data into a coded version using algorithms and keys, making it unreadable without the correct key.

What is a digital signature?

A digital signature is a cryptographic technique that verifies the authenticity and integrity of a message or document.
