Detailed explanation-1: -The known-plaintext attack (KPA) is an attack model for cryptanalysis where the attacker has access to both the plaintext (called a crib), and its encrypted version (ciphertext).
Detailed explanation-2: -Cryptanalysis techniques and attacks In a ciphertext-only attack, the attacker only has access to one or more encrypted messages but knows nothing about the plaintext data, the encryption algorithm being used or any data about the cryptographic key being used.
Detailed explanation-3: -Cryptographic attacks. Cryptographic attacks are used by cryptanalysts to recover plaintext without a key.
Detailed explanation-4: -Chosen Plaintext Attack (CPA) − In this method, the attacker has the text of his choice encrypted. So he has the ciphertext-plaintext pair of his choice. This simplifies his task of determining the encryption key.
