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.
6 days ago · Cryptography is a technique of securing communication by converting plain text into ciphertext. It involves various algorithms and protocols to ensure data confidentiality, integrity, authentication, and non-repudiation. In this article, we will discuss cryptography and its types.
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.
In our modern digital age, cryptography has become an essential cybersecurity tool for protecting sensitive information from hackers and other cybercriminals. Derived from the Greek word “kryptos,” meaning hidden, cryptography literally translates to “hidden writing.”
Cryptography is the technique of obfuscating or coding data, ensuring that only the person who is meant to see the information–and has the key to break the code–can read it. The word is a hybrid of two Greek words: “kryptós”, which means hidden, and “graphein”, which means to write.
Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία-logia, "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior.
Cryptography refers to the techniques and algorithms that are used today for secure communication and data in storage. It incorporates mathematics, computer science, electronics and digital signal processing. Broadly speaking, there are four types of cryptography systems:
May 22, 2022 · Cryptography definition. Cryptography is the art of keeping information secure by transforming it into form that unintended recipients cannot understand.
Apr 21, 2022 · Cryptography is a form of securing digital data and messages often using special keys that only the sender and recipient have access to. Cryptography uses mathematical systems and algorithms to encrypt and decrypt data. Symmetrical cryptography uses the same key for both encryption and decryption.
1. : secret writing. 2. : the enciphering and deciphering of messages in secret code or cipher. also : the computerized encoding and decoding of information. 3. : cryptanalysis. Did you know? For a word having to do with secrets, cryptography has a surprisingly transparent origin.
