This cybersecurity practice, also known as cryptology, combines various disciplines like computer science, engineering, and mathematics to create complex codes that hide the true meaning of a message. Cryptography can be traced all the way back to ancient Egyptian hieroglyphics but remains vital to ...

Gavin Andresen, Bitcoin’s technical lead, told Forbes.com that cryptocurrency is designed to bring back a “decentralized currency of the people,” meaning cryptocurrency takes centralized banks out of the equation. Because Bitcoins must be cryptographically signed each time they are transferred, each...
what is the correct meaning of encryption? Byanon89442— On Jun 10, 2010 Cryptography is a wide term which encapsulates both encryption and decryption of data. Cryptography, i.e. encryption and decryption, are done by using the cryptographic algorithms which are mathematics based. Cryptography algo...
The word comes from the Greek word "kryptos," meaning 'secret' or 'hidden.' The literal translation for cryptography is "secret writing." It comes from the study of cryptology, the art of breaking codes or ancient hieroglyphics and solving them. Data encryption is one of the most important...

2) What Is the Meaning of Block Size? Every algorithm processes block ciphers in a particular size. In other words,the algorithm “breaks” the data or plaintext into blocks and processes the calculations block by block. Every block contains a fixed size of bits: for example (as shown abov...
What is Cryptography? The term “cryptography,” derived from “crypt” meaning “hidden” and “graphy” meaning “writing,” is the study of encrypting and decrypting data to prevent unauthorized access to the data. Codes are used to protect the information so that only the intended people ca...

digest is always the same if you supply the same plaintext input. Additionally, if you make even a small change to the plaintext, the hash digest output is completely different. The combination of these two features makes hashing algorithms useful in cryptography. A common use is with ...
