Imagine you're a hosting provider and you want to generate cryptographic keys. Lots of them. On virtual machines. Pretty soon you'll find out that computers are indeed very logical devices, which makes them particularly bad at coming up with random data. And guess what makes or breaks a cryptographic key? That's right: random data. In this post we will show you how we tackled this problem at Greenhost. To clarify how we are working and hopefully to also share some of our knowledge to the wider community."

Greenhost remains involved in the project to ensure the security and stability of the platform.
