HPKP: What is behind the public-key pinning extension for HTTP

SSL/TLS certificates play an increasingly important role in the transmission of sensitive data. They guarantee that data packets reach the desired addressee without any detours.

OAuth & OAuth 2: data usage across platforms

The “pathway to hell” – this is how Eran Hammer-Lahav once called the security protocol OAuth 2.0, on which he himself had worked for years. Others, however, use the service without issue.

What is FIDO2?

FIDO2: The new standard for secure web log-in

Passwords are not an ideal way to surf the World Wide Web safely. They are either so complex that they are hard to remember, or so simple that they can be guessed in next to no time.

Passwords have long ceased to offer sufficient protection when surfing the internet: They are easy to crack, easily tapped, and difficult to remember.

How does it work?
