Scientist, safecracker, etc. McDevitt Professor of Computer Science and Law at Georgetown. Formerly UPenn, Bell Labs. So-called expert on election security and stuff. https://twitter.com/mattblaze on the Twitter. Slow photographer. Radio nerd. Blogs occasionally at https://www.mattblaze.org/blog . I probably won't see your DM; use something else. He/Him. Uses this wrong.

I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the #CHERI project, where I led the early language / compiler strand of the research, and am the maintainer of the #CHERIoT Platform.

I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler.

Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion. Shake well before opening. Keep refrigerated.

Founder of DEF CON & Black Hat. Maintainer of infocon.org.

Member of the UK Gov Cybersecurity Advisory Board & The Council on Foreign Relations.

Working to get Hackers and Researchers a seat at the Policy table.

I'm interested in hacking, community, technology, privacy, security policy, and the intersection of civil society. (He/Him) Opinions are my own.

Cryptography, privacy, quantum security, infosec, retro vibes.

I am a mathematician and computer security scientist, with a strong interest in cryptography and anonymity, specialized in quantum security and complex cryptographic protocols. I am also a privacy hacktivist and public speaker, blahblahblah, read my Linkedin bio for this s**t, this is my Mastodon corner.

I co-develop Shufflecake, an open source privacy disk encryption tool to help journalists, activists, and whistleblowers evade unjust prosecution.

I am an advocate of digital self-sovereignty. You will see me often ranting about Big Tech, enshittification, and surveillance capitalism.

Fascinated with anime, Japan, RPGs, retro computing, and all things 80-90's. Notice I wrote "fascinated", not "knowledgeable".

Here you won't find peace nor forgiveness, but just: #cryptography #privacy #quantum #security #infosec #retro vibes!

Used to help run Fosstodon. These days, I just hang out here.

I work in InfoSec and live with two kids, one wife, two dogs, a blind cat, a flock of 25 chickens, 8 goats, and more fish than I can count.

Also into watches and motorbikes — both riding and wrenching.

I also run @purecommons.

I once worked with goats. I moved into tech.This was a mistake. 
Expect sheep, wool, and textile history. Also birbs. Infosec on occasion. 
I use content warnings for topics and images that can trigger PTSD. I do not use them to shield people ***without*** trauma from experiencing racism, sexism, transphobia, and other forms of discrimination. If you can ignore politics, you’re not likely in need of content warnings for much of anything, really.
