Security Incident - New keys to sign container images and helm charts for openDesk 1.19.0

As part of a CI modernization our keys for signing container images and helm charts for openDesk have been leaked accidentally. 

As for now there are no known compromising incidents caused by this leak. 

For our upcoming release 1.19.0 we will sign all container images and helm charts with newly created keys to regain a secure infrastructure.

Until then users should refrain from obtaining openDesk and it's components from 3rd parties, which may have been signed with the leaked keys.

We recommend an immediate update once openDesk 1.19.0 has been released.
