What is the importance of cryptography in ensuring privacy?

Cryptography is essential for protecting sensitive information by converting it into a secure format that unauthorized users cannot access.

Can you explain how encryption works?

Sure! Encryption transforms readable data into an unreadable format using algorithms and keys, ensuring only authorized parties can decrypt it.

What are some common encryption methods used today?

Common methods include AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and ECC (Elliptic Curve Cryptography).

How does cryptography help in online transactions?

It secures online transactions by encrypting sensitive data like credit card numbers, making it difficult for hackers to intercept.

Are there any risks associated with cryptography?

Yes, risks include key management issues, potential vulnerabilities in algorithms, and the possibility of quantum computing breaking current encryption.
