Satharus/README.md

Hello! 👋

I am Ahmed Elmayyah (AKA Satharus in some places), I graduated from the Faculty of Computer and Information Sciences, Computer Systems Department, Ain Shams University in July 2021. I’m a cybersecurity enthusiast and researcher, tinkerer, and a strong supporter of free/libre software and decentralisation. I currently work as a Hardware Security Researcher. Sometimes I do purple-teaming too. I am also a GCFA and an eCRE.

I like cycling, progressive rock, videogames (add me on Steam), electronics and hardware, and computers. Currently, I am currently living in Bristol, England.

"Satharus" was the name of my characters in a couple of RPG games during high school and it just kinda stuck with me.

That's pretty much all there is to it 😃.

I usually like to tinker with low level programming, reverse engineering, Linux, and hardware and stuff. Here's some of the work I am proud of, in no particular order:

  • The 4043: A Ben Eater-inspired Turing complete 8Bit breadboard computer using TTL chips, presented in a blog post trilogy which explains computer architecture and how it would map to such a project
  • Check out some of my Bash Snippets
  • Full 128-bit AES Encryption written in x86 assembly without using the AES-NI extension. Alongside is the NASM template for writing quick assembly programs
  • The not so chad shell
  • The (forever) WIP GDB interface: Disass

Not strictly software, but related:
