WebApr 23, 2024 · Basically, cryptography serves as a technique for the transmission of secure messages among two or more participants. The sender leverages a specific type of key and algorithm for encryption of a message before sending it to the receiver. Then, the receiver employs decryption for obtaining the original message. WebCryptography – Greek for hidden and writing is a means of transforming data in a way that renders it unreadable by anyone except the intended recipient. What was originally used …

Cryptography is the mathematical foundation on which one builds secure systems. It studies ways of securely storing, transmitting, and processing information. Understanding what cryptographic primitives can do, and how they can be composed together, is necessary to build secure systems, but not su cient.
