Official repo and demo⁠

⁠Installation and usage

The easiest way is to use Docker image:

$ docker run -d -v /home/<ssh-user>/.ssh:/root/.ssh -p 127.0.0.1:8080:8080 eraclitux/ssh-key-editor

The daemon con only be accessed locally for security reasons, to access the web interface with a remote browser use ssh tunnelling:

ssh -v -ND 8081 <user>@<bastion-host>

and configure you browser to use it⁠ taking care to direct traffic on tunnel even for localhost, visit http://localhost:8080/ with your browser.

⁠Change default password

To change the default password defined in the Dockerfile just pass a custom one when starting container using -e HTTP_PASSWORD=<my-passwd>.

⁠Security considerations

Misconfiguration of this tool leads to serious security issues as unauthorized shell access. Never bind on public interfaces, if risk can be taken use an http reverse proxy with proper TLS termination to access from the internet otherwise basic auth credentials could be easily sniffed.

Always follow SSH good practices, disable access for root and always mount a normal (at most sudoer) user's .ssh with -v.
