I'm not entire sure this is useful, since the time when people need this (when configuring the SP in Ipsilon), they most likely have already closed the terminal they ran ipsilon-client-installer in, and they will need to get this information the manual way again.

I think it would be more useful to just document this somewhere.

Just wondering why this change? I think we should not encourage people to keep certificates for 10 years.

If someone really wants to use a certificate that's valid for 10 years, I would suggest them to generate it themselves outside of Ipsilon.

I agree with @puiterwijk here.

Is this PR still relevant?
