What is Cryptography? Definition from SearchSecurity

WebCryptography studies techniques aimed at securing communication in the presence of adversaries. While encryption is probably the most prominent example of a crypto- graphic problem, modern cryptography is much more than that. WebCryptography is the study of securing communications from outside observers. Encryption algorithms take the original message, or plaintext, and converts it into ciphertext, which is not understandable. The key allows the user to decrypt the message, thus ensuring on they can read the message.
