Chrome Key emulates a Hardware Authentication Device. It is capable of answering Webauthn requests for both registering new keys and authenticating with existing ones.
The purpose is to allow developers to test their applications without requiring having an actual device in hand.
It relies on browser standards such as Web Cryptography API and Concise Binary Object Representation for generation and interaction with key material.
This will never be able to provide the same security guarantees as a real HAD, so use it for development, debugging and testing only.
A 3-post blog series was written, touching different portions of this extension, its guarantees and lack of. The first post of the series may be found here https://blog.joaopeixoto.net/chrome-key-an-extension-story/.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
