WebCryptography can roughly be divided into symmetric key and public key (asymmetric key) cryptographies. The symmetric key cryptography uses the same secret key for encryption and decryption. With the processing that is relatively lightweight, it is used in data encryption and authentication. WebCryptography (or cryptology; from Greek κρυπτός, kryptos, "hidden, secret"; and γράφ, gráph, "writing", or -λογία, -logia, respectively) is the practice and study of hiding information. …

WebWhat is asymmetric cryptography? Asymmetric cryptography, also known as public-key cryptography, is a process that uses a pair of related keys -- one public key and one private key -- to encrypt and decrypt a message and protect it from unauthorized access or use. WebCryptography is an indispensable tool for protecting information in computer systems. In this course you will learn the inner workings of cryptographic systems and how to correctly use them in real-world applications.
