Answer 1

The type of attack being conducted when the attacker has messages in both encrypted form (ciphertext) and decrypted form (plaintext) is called a **Known-Plaintext** attack.

In a Known-Plaintext attack, the attacker has access to both the plaintext and the corresponding ciphertext, which can help them deduce the key or the algorithm used for encryption.
