Length Extension Attack Demonstration (Video)
This is a video version of my blog post, Length Extension Attack. In it, I talk through the theory of length extension attacks and demonstrate an SHA-1 length extension attack against an (imaginary) website.

Length Extension Attack Demonstration
Hash length extension attacks aren't necessarily intuitive without a little understanding of how vulnerable hashing algorithms work. Using SHA1 as an example, I've put together a step-by-step demonstration with a focus on teaching the underlying principles behind the vulnerability.

Tension in the Wires
Received my physical copy of Planets In The Wires today, and I must say it was really cool of Pagan Wanderer Lu to include one of Fred "Thickie" Holden's famous Tension Sheets as a freebie.

Emoji Reactions
I added a stupid feature to my blog.
On some posts, including this one, you can now send an "emoji reaction". Y'know, for if you're too lazy to write a comment.
The available reactions vary by post.
That is all. -
The Frosted Pane
Pagan Wanderer Lu's new album Planets In The Wires dropped today, and I just cried my eyes out at track 5 (The Frosted Pane).
It opens almost apologetically, like an explanation for the gap in new releases for most of the twenty-teens. But it quickly becomes a poetic exploration of a detached depression of a man trapped under the weight of the world. It's sad, and beautiful, and relatable. -
It Takes Two
At the weekend, Ruth and I travelled to Edinburgh to attend a tango class for which we were in no-way qualified. We learned a lot, but mostly because we knew very little to begin with!

ET App
Travelling around Edinburgh by tram this weekend, I kept being advertised the "ET app".
I didn't install the app, in case it was bundled with spyware.
After all, everybody my age knows: ET phones home.

I'm a fierce bunny rabbit! -
Gemini Squared
How did I never think of accessing Gemini (the protocol) on my Gemini (portable computer) before today?
Of course, I recently rehomed my Gemini so instead I had to access Gemini on my Cosmo. -

I just read a comic book full of early-Internet nostalgia that delighted me, and wanted to share it with you.
