Ssh-2 keygen: Expiration Date for Key?

Hello,

On Legacy Linux 7.2, I have used this command to generate an ssh-2 key:

ssh-keygen -b 1024 -t rsa

I need to know: Does this key have an expiration date?

How can I display the expiration date if it has one?

Thank you!

No, as far as I know.
Expiration date is included in certificates though.

Hi zby,

Thank you for the reply.

Last year one of our customers said our key is expiring,
and requested a new key.

That made me update our rsa authentication key for all our customers.

It is now one year since that replacement key was distributed.

I am anticipating having to replace it again.

So far, no one has requested a replacement. No one is
claiming it is about to expire.

That is fine, except I would not like it to expire, say,
in July instead of May. At that point I am likely to be
away on vacation, and there will be no one available
at my shop to respond. Until I return.

To the developers of ssh-2: please add support to
display key expiration dates. If none, say so in the
RFC.
