Ransomware is a new type of virus trojan that has emerged alongside the rise of digital currencies. It typically spreads through various forms such as brute force cracking, exploiting vulnerabilities, spam emails, and bundled software. Once a machine is attacked by ransomware, most files will be modified by encryption algorithms and have a special suffix … Read more
Before reading this chapter, please first understand the theory of encoding and decoding in computer basics and an introduction to OpenSSL.What is the relationship between binary, hexadecimal, bytes, and strings? HTTPS, certificates, data encryption… How many of these OpenSSL skills have you used? Below is the main content Encryption Algorithms In API integration, commonly used … Read more
From the previous test (Performance Comparison of Different Encryption Algorithms in OpenVPN), we found that there are differences in forwarding performance when OpenVPN uses different encryption algorithms, as shown below: Comparing the encryption algorithms, we can see that the specific encryption algorithms are divided into three parts: the first part is the algorithm name, which … Read more
Author: 0pening 1. Introduction Testing a certain WeChat mini program, without further ado, let’s start using BurpSuite to capture packets. However, upon capturing the packets, I noticed something was off 🤨. This application encrypts the parameters into bizContent and uses a signature parameter sign to prevent man-in-the-middle attacks on the data packets… not very honorable. … Read more
In the rapidly advancing field of technology, every breakthrough in quantum computing attracts significant attention. Recently, a piece of news regarding C# and quantum computing has caused a stir in the tech community: developers have attempted to break encryption algorithms using a hybrid development approach with C# and Q#, which unexpectedly led to a data … Read more
We previously introduced that the forwarding performance of IPsec VPN varies with different encryption algorithms (using vSRX to test the performance differences of various IPsec VPN encryption algorithms), but does OpenVPN have this issue? First, we need to confirm the algorithm information used during the OpenVPN negotiation process. For the default configuration, the algorithm information … Read more
