What is a Certificate? A digital certificate makes use of Public Key Cryptography to authenticate users, essentially blending a Public Key with a Digital Signature to assert identity. The most common standard used for certificates is X.509 and common uses of certificates include: Secure web browsing – HTTPS – encryption

Getting Started with the Nitrokey HSM 2
The folks at Nitrokey kindly sent me a Nitrokey HSM 2 as part of the Nitrokey Community Program. The tiny, thumb-drive sized device is actually a Hardware Security Module, a device that holds cryptographic keys and performs encryption and decryption. If you’ve not come across HSMs before and you’d like
Joining the Nitrokey Community Programme
I first came across Nitrokey as a provider of U2F USB sticks, little hardware devices that authenticate users with a physical device. The idea there is that you can use this physical device as part of a multifactor authentication process to strengthen your security. Using a physical device means that
