What are some common cryptography techniques?

Common cryptography techniques include symmetric encryption, asymmetric encryption, hashing, and digital signatures.

Can you explain symmetric encryption?

Symmetric encryption uses the same key for both encryption and decryption, making it fast but requiring secure key management.

What about asymmetric encryption?

Asymmetric encryption uses a pair of keys: a public key for encryption and a private key for decryption, enhancing security.

What is hashing used for?

Hashing is used to convert data into a fixed-size string of characters, which is typically a hash value, for data integrity.

Can you give an example of a digital signature?

A digital signature is like a handwritten signature but more secure; it verifies the authenticity of a digital message or document.
