Cryptography vs. Cryptanalysis

Cryptographynoun

The discipline concerned with communication security (eg, confidentiality of messages, integrity of messages, sender authentication, non-repudiation of messages, and many other related issues), regardless of the used medium such as pencil and paper or computers.

Cryptographynoun

The act or art of writing in code or secret characters; also, secret characters, codes or ciphers, or messages written in a secret code.

Cryptographynoun

The science which studies methods for encoding messages so that they can be read only by a person who knows the secret information required for decoding, called the key; it includes cryptanalysis, the science of decoding encrypted messages without possessing the proper key, and has several other branches; see for example steganography.

Cryptographynoun

the science of analyzing and deciphering codes and ciphers and cryptograms

Cryptographynoun

act of writing in code or cipher

Cryptography

Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós and γράφειν graphein, , or -λογία -logia, , respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography.

Cryptanalysisnoun

The science of analyzing and breaking of codes and ciphers.

Cryptanalysisnoun

An analysis or decrypting of a specific text or a specific code or cipher.

Cryptanalysisnoun

the science which studies methods to discovering the secret meaning of encrypted messages for which one does not possess the secret decoding information (called the key).

Cryptanalysisnoun

the methods and procedures used to discover the secret meaning hidden in encrypted messages.

Cryptanalysisnoun

the science of analyzing and deciphering codes and ciphers and cryptograms

Cryptanalysis

Cryptanalysis (from the Greek kryptós, , and analýein, ) is the study of analyzing information systems in order to study the hidden aspects of the systems. Cryptanalysis is used to breach cryptographic security systems and gain access to the contents of encrypted messages, even if the cryptographic key is unknown.
