What is a brute-force attack in cryptography?
An attack that uses mathematical formulas to decrypt data.
An attack that involves trying all possible keys to decrypt the data.
An attack that involves manipulating the key during encryption.
An attack that exploits weak encryption algorithms.
Which of the following is a type of attack that tries to discover the encryption key by analyzing patterns in ciphertext?

Man-in-the-middle attack
Which attack involves intercepting and altering the communication between two parties without their knowledge?

Chosen-plaintext attack
Differential attack
In which type of cryptographic attack does the attacker have access to both the plaintext and its corresponding ciphertext?
Known-plaintext attack
Chosen-ciphertext attack
