Source: https://www.biaodianfu.com/aes.html The Data Encryption Standard (DES) has a key length of 56 bits, resulting in a theoretical security strength of 256. However, the late 20th century was a period of rapid development in computing, and advancements in component manufacturing technology led to increasing computational power, making DES insufficiently secure. On January 2, 1997, the … Read more

JCL: The Alchemist of Java Encryption Algorithms! Hello, friends! Today, Niu Ge will talk to you about the popular topic of Java encryption algorithms. Do you remember how confused I was the first time I encountered encryption algorithms when I transitioned from testing to Java? It was like stepping into the kitchen for the first … Read more
There are two sayings: 1) Algorithms and data structures are an important part of programming. If you lose algorithms and data structures, you lose everything. 2) Programming is algorithms and data structures; algorithms and data structures are the soul of programming. Note that this is not my own statement, but a summary from countless programmers. … Read more
Wireless networks can provide significant business advantages for enterprises, such as ensuring employees can connect across multiple devices and even buildings, thereby improving productivity. However, wireless networks can also bring visible and invisible risks to business privacy. Below are nine common wireless network security pitfalls that enterprises should pay attention to. As BYOD continues to … Read more
A few days ago, I started writing a series of articles about tools and methods for unpacking malware. Each piece of malware or packer is different, and sometimes a universal method cannot be used for unpacking. However, common characteristics can sometimes be found. For example, packers often use weak encryption algorithms, and breaking these algorithms … Read more
