If it's so easy to guess a uuid, here you go

I ran crypto.randomUUID() twice on my machine.

The first ID was 15041508-fd38-4eda-bc1d-7b74e4738cd9

I encrypted a text file with the following command:

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com.

My First Volatility Plugin with Unified Output

Although there are many excellent resources for learning Volatility available (The Art of Memory Forensics book, the vol-users mailing list, the Volatility Labs blog, and the Memory Analysis training course to name a few), I've never really seen a good absolute beginners guide to writing your first plugin. So if you find yourself needing that, hopefully this will help.

Also, it's worth checking out @jameshabben's post on the topic.
