Web• Cryptography is a technique to provide message confidentiality. • The term cryptography is a Greek word which means “secret writing”. • It is an art and science of transforming messages so as to make them secure and immune to attacks. • Cryptography involves the process of encryption and decryption. This process is depicted. WebFeb 6, 2024 · What Does Cryptography Mean? Cryptography involves creating written or generated codes that allow information to be kept secret. Cryptography converts data into a format that is unreadable for an unauthorized user, allowing it to be transmitted without unauthorized entities decoding it back into a readable format, thus compromising the data. sims 4 new pack redactedhttp://www.facweb.iitkgp.ac.in/~sourav/lecture_note1.pdf rccg winners place
