Detailed explanation-1: -2) Cryptography: the art of creating and using a cryptosystem. 3) Cryptanalysis: the art of breaking cryptosystems-seeing through the disguise even when you’re not supposed to be able to. 4) Cryptology: the study of both cryptography and cryptanalysis.

Detailed explanation-2: -Cryptography creates messages with hidden meaning; cryptanalysis is the science of breaking those encrypted messages to recover their meaning. Many use the term cryptography in place of cryptology; however, it is important to remember that cryptology encompasses both cryptography and cryptanalysis.

Detailed explanation-3: -is the art & science of cracking the cipher-text without knowing the key. Explanation: Cryptanalysis is the art & science of cracking the cipher-text without knowing the key. This technique is also implemented for designing new cryptographic algorithms or to test their strengths.

Detailed explanation-4: -Cryptanalysis is the study of methods for obtaining the meaning of encrypted information, without access to the secret information that is typically required to do so. Typically, this involves knowing how the system works and finding a secret key. Cryptanalysis is also referred to as codebreaking or cracking the code.
