Re: [PATCH v6 0/9] ssh signing: Add commit & tag signing/verification via SSH keys using ssh-keygen

> openssh 8.7 will add valid-after, valid-before options to the allowed keys
> keyring. This allows us to pass the commit timestamp to the verification
> call and make key rollover possible and still be able to verify older
> commits. Set valid-after=NOW when adding your key to the keyring and set
> valid-before to make it fail if used after a certain date. Software like
> gitolite/github or corporate automation can do this automatically when ssh
> push keys are addded / removed I will add this feature in a follow up patch
> afterwards.
