What is cryptography?
Cryptography is the practice of securing communications by transforming readable data into an unreadable form (ciphertext) and back again using keys, to ensure confidentiality, integrity, and authenticity.
What is a cryptographic hash function and what properties does it have?
A hash function maps data to a fixed-size output (hash) that is deterministic, quick to compute, and resistant to preimage, second-preimage, and collision attacks, making it useful for integrity checks and password storage.
What is the difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for encryption and decryption, offering speed but requiring secure key sharing. Asymmetric encryption uses a public/private key pair, enabling secure key exchange and digital signatures, but typically slower.
What is a digital signature and why is it important?
A digital signature is created with a private key and verified with the corresponding public key, proving who sent a message and that it has not been altered.
