La cryptographie vise à sécuriser des informations et à les dissimuler aux yeux des tiers via le chiffrement. Bien que cette méthode existe sous une certaine forme depuis des millénaires, l’impact de la cryptographie moderne dans la sécurité des informations est plus récent. Dans cet article, nous expliquons en quoi consiste la cryptographie, son importance…

Cryptography is the process of securing and hiding information from unauthorized parties. While it has existed in some form for thousands of years, modern cryptography only became an integral part of everyday information security over the last few decades. So, what is cryptographic technology, how does it work, and why is it important? Read on…

Block and stream ciphers are the two main types of symmetric key algorithms. Both ciphers use the same cryptographic key to encrypt and decrypt data, but that’s where their similarity ends. Find out how block and stream ciphers work, how they defer, and the best contexts to use them. Contents What is a block cipher?…

Blowfish encryption is a symmetric-key block cipher usually used in file encryption, VPNs, and password hashing. It was introduced in 1993 and became a go-to encryption method because of its efficient encryption and decryption processes. However, Blowfish is slowly being replaced by newer, more secure algorithms such as AES. This article will look at the…
