Did NSA Put a Secret Backdoor in New Encryption Standard? (2007)
Random numbers are critical for cryptography: for encryption keys, random authentication challenges, initialization vectors, nonces, key-agreement schemes, generating prime numbers and so on. Break the random-number generator, and most of the time you break the entire security system. Which is why you should worry…

How to build a windmill
Windmills have always fascinated me and for a long time I was dreaming of one day building my own. Where I live there are still machines from the 1600’s that are just as magnificent today as when they were first built. When you see one standing in a field rotating and converting passing air into usable energy they…

“iCloud Backup”
Last year, I bought my 87-year-old grandfather an iPad 2 to replace the who-knows-what PC that was frustrating him constantly. He only used the PC for email and playing music, so it was a no-brainer.

Life as a Service
I was born on a rainy morning, the 20th of March 1965, 3:15 am on the outskirts of a big European city. There wasn’t much to do for me other than to drink my milk so I’m kind of surprised that I don’t remember the man with the contract that I signed within a few hours of being born. Stupid me. I really shouldn’t have…

Go Bloviations
This post was written sixteen months ago, when fish briefly explored Go with the intention of writing a new command line shell. ( fish abandoned Go after discovering that terminal programming is what makes shells so horrible, and term programming is least horrible in C.)

SHA-3 to Be Announced
NIST is about to announce the new hash algorithm that will become SHA-3. This is the result of a six-year competition, and my own Skein is one of the five remaining finalists (out of an initial 64). It’s probably too late for me to affect the final decision, but I am hoping for “no award.” It’s not that the new hash…
