Keys in Docker Trust Content
Cryptographic keys play an important role in DCT and it will check the authenticity of the image user. it is the vital component of Docker’s security framework, Docker Content Trust (DCT) Keys guarantee the integrity and validity of the container images. it is also called as safety guards.
Types of DCT Keys
- Private Key : it plays a critical role in DCT. as per it’s name it keeps private and only publisher knows about it. and it is used to sign the image and the image verification. and it is recommend to keep it safe and private.
- Public Key : the public key is available for the users It is used to verify the integrity and authenticity of signed Docker images. but difference is it made available for docker clients to validate the signatures that are associated to it It is an additional cryptographic key meant for public which is used for distribution and accessibility.
If you want to know more about it you can go through Private vs Public key.
What Is Docker Trust Content ?
When we are using Docker images, we must think about whether the image we are using is trustworthy or not, because trust is a central concern in every field. especially when we download external resources from our local system. In this scenario, Docker comes up with a special security feature called Docker Content Trust (DCT).
