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 and decrypt data, ensuring that only authorized parties can access it.

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.

What are some common algorithms used in cryptography?

Common algorithms include AES (Advanced Encryption Standard) for symmetric encryption and RSA (Rivest-Shamir-Adleman) for asymmetric encryption.

How does cryptography ensure data integrity?

Cryptography ensures data integrity through techniques like hashing, which creates a unique hash value for data. If the data changes, the hash will also change, indicating tampering.
