Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively [1]), is the practice and study of techniques for secure communication in the presence of adversarial behavior. [2]
Cryptography is a technique of securing information and communications using codes to ensure confidentiality, integrity and authentication. Thus, preventing unauthorized access to information. The prefix "crypt" means "hidden" and the suffix "graphy" means "writing".
Cryptography is the practice of developing and using coded algorithms to protect and obscure transmitted information so that it may only be read by those with the permission and ability to decrypt it.
In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher.
Cryptography, as defined in the introduction to this article, is the science of transforming information into a form that is impossible or infeasible to duplicate or undo without knowledge of a secret key.
Cryptography is an important computer security tool that deals with techniques to store and transmit information in ways that prevent unauthorized access or interference.
This comprehensive guide delves into the fundamental aspects of cryptography in computer science, emphasizing its pivotal role in digital security and communication. It explores cryptography's evolution from ancient techniques to modern applications like blockchain and cryptocurrency. The article addresses key cryptography concepts, including encryption methods, cryptographic keys, and types ...
Cryptography provides a method for secure communication through sophisticated mathematical equations (algorithms) and, often, secret keys. Three main types of cryptographic algorithms include symmetric encryption, asymmetric encryption, and hash functions.
Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce.
