1. Introduction 1.1 Ransomware Ransomware is a type of malicious software that runs on computers, kidnapping user files and rendering user data assets or computing resources unusable, and extorting money from users as a condition for restoring access. These user data assets include various files such as documents, databases, source code, images, and compressed files. … Read more
Privacy protection? It’s not to scare everyone; information is transparent, but we should still try to maintain personal privacy. Today, we will learn about symmetric encryption and asymmetric encryption. First, let’s read this character “钥”, is it pronounced “yao” or “yue”? Check the image below. 1. Symmetric Encryption As the name suggests, in symmetric encryption, … Read more
Follow “Script Home” and join millions of developers Author | kiba518 Produced by | Script Home (ID: jb51net) Introduction This article mainly explains the commonly used encryption algorithms in C#.

A Revolutionary Algorithm Earth-Shattering A cryptographic algorithm that can only be cracked by computational power 1 The History of Cryptography 5th Century BC, the ancient Greeks used a stick called scytale to transmit encrypted messages. To encrypt, a strip of paper was wrapped around the stick, and the message was written horizontally along the stick. … Read more
A few days ago, I began writing a series of articles about tools and methods for unpacking malware. Each malware or packer is different, and sometimes general methods do not work for unpacking. However, common characteristics can sometimes be found among them. For example, packers often use weak encryption algorithms, which can be cracked. In … Read more
