I'm working on a small server written in Go to add short-lived user certificates to the forwarded agents of authorized users. https://github.com/rorycl/sshagentca This seems to work quite well for accessing sshd servers with the appropriately configured "TrustedUserCAKeys" directive. I have been in a debate about how similarly adding host certificates to forwarded agents could help mitigate man-in-the-middle attacks. This has raised a few questio...

...ssh, might it not be worth considering an ssh certificate signing authority? I've made the proof-of-concept noted below, which adds certificates to forwarded agents. It doesn't need shell accounts, but prsently requires ssh public keys to be added to a yaml file: https://github.com/rorycl/sshagentca Cheers, Rory

G'day, In our infrastructure we're trying to be more diligent about switching to sk keys (and/or certs backed by sk keys.) However, there are some services like Gerrit and Jenkins which are written in java and I guess they will never support sk keys, or at least, it seems like it won't happen any time soon. For such services, typical practices at the moment include putting

Hi, We have a CLI that certain users get dropped into when they log in. One of the things they can go is generate certificates (actually .p12 key/certificate bundles) that they will then scp out of the box from another host. Problem is that if their default shell isn't sh, ash, dash, bash, zsh, etc. then things break. Is there a workaround to allow scp/sftp to continue to work even for

Hi, We're developing an open source project that uses SSH certificates. We issue short lived certificates (few minutes) to execute commands on behalf of users. We have a use case where we need to issue certificates with 10 days validity and store them, so we put a command inside them: ssh-keygen -s ca-key -I certN -n user -O force-command="wget something" -V +10d user-key.pub and
