Cryptography

Passwords are the most popular method for implementing an authentication system despite their security issues. As a result, a cat-and-mouse game between hackers...

A blockchain is a record of digital transactions. It is a distributed software network which can function both as a digital ledger and as a mechanism allowing...

Blockchain is a technology that has gained a great deal of attention in recent years. The goal of a blockchain network is to create an immutable digital ledger...

Virtual Private Networks (VPNs) are a solution designed to provide a secure connection between two parties over an untrusted network. Traffic is encrypted...

The internet and many other digital systems rely upon public key infrastructure (PKI) to manage trust within a system. PKI includes a number of different...

Hash functions are unique because they use cryptographic primitives and principles but are not cryptographic algorithms. Unlike symmetric and asymmetric encryption...

Asymmetric cryptography differs from symmetric cryptography in that it uses two encryption keys: a public key and a private key. These keys are related by...

Cryptography can seem complex, but a lot of cryptography boils down to some very simple mathematical operators and structures. In this article, we talk about...

Symmetric cryptography gets its name from the fact that the same secret key is used for encryption and decryption, thus making the process symmetrical. The...

Cryptology — literally “the study of secrets” — is composed of cryptography (making codes) and cryptanalysis (breaking codes). However, many people...
