Tamuro meetup in London posted June 2018

I will be at the Tamuro meetup in London tonight (at the George Inn pub). It's a meetup about security and cryptography. Feel free to join if you want to grab a beer and talk about supersingular isogenies.

Well done! You've reached the end of my post. Now you can leave me a comment :)
