![]() Yes, this is 7zip's random generation code running on your computers in 2019. He was astonished to notice that initialization vector generating algorithm was written very poorly. Michal Stanek / a programmer casually started to audit the codebase after planning to encrypt some files. A dramatic twist in events: the AES implementation in 7z format is accused of not complying crypto standards. With built-in AES-256 encryption support, people often use it for quick encrypted archiving. The 7z format is open and modular, similar to other popular archive formats like tar. The developer, Igor Pavlov is also behind the superior LZMA for data compression which is the basis of 7-Zip’s native 7z format. With the rapid development on free and open source front, 7-Zip (also written as 7zip or Sevenzip) started to shine. WinZip was a must-have piece of software for Wintel users (we didn’t call them app then!), which was later replaced by WinRAR. I was circling around the amazing power compression techniques which was also helpful for getting scene ripped games. Later on, I stumbled on ripping audio CDs and DVD movies. It was early 2000, and someone enchanted me by nothing but zipping handful of files to carry inside a 3.5 inch floppy which was not possible earlier. ![]() ![]() It was a magical moment when I learned about compression. ![]()
