Troy Hunt

Since launching version 2 of Pwned Passwords with the k-anonymity model just over 2 years ago now, the thing has really gone nuts (read that blog post for background otherwise nothing from here on will make much sense).

Troy Hunt

Ever notice how there was a massive gap of almost 9 months between announcing the intention to start open sourcing Have I Been Pwned (HIBP) in August last year and then finally a couple of weeks ago, actually taking the first step with Pwned Passwords ?
