Re: keys only auth

I'm following this guide:


Which is under:


As you can see it uses NSS for key generation and storage.

I actually got rsa key auth to work with StrongSwan but it seems less stable than Libre (was dropping connections and slow to re-establish).

Yes I know the syntax for adding alt subject names, thanks. The problem is Mikrotik wants something specific there (from server cert) and I can't figure out what, it seems undocumented. Some people say it wants an email address (any email address) but that didn't work.

Anyway to keep from straying too far...

...has anyone used rsa key *only* auth with Libre where the other side was a different system (not Libre)? How did you manage your keys?

Any suggestions on keys management?
