How does cryptography protect data?

What is cryptography and how does it work?

Cryptography is the practice of securing information by transforming it into an unreadable format. It uses algorithms to encrypt data, making it accessible only to those who have the decryption key.

Can you explain the difference between symmetric and asymmetric encryption?

Sure! Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys: a public key for encryption and a private key for decryption.

How does cryptography protect data during transmission?

Cryptography protects data during transmission by encrypting it before sending. This ensures that even if the data is intercepted, it cannot be read without the decryption key.

What are some common cryptographic algorithms?

Some common cryptographic algorithms include AES (Advanced Encryption Standard), RSA (Rivest-Shamir-Adleman), and SHA (Secure Hash Algorithm). Each serves different purposes in securing data.
