[cisco-voip] VCS 8.2 won't accept Trusted CA Cert with expiration date of 40 years from now - shows it as expired Dec 31, 1969

[Brian V]

Thanks for the heads up.   That seems to be my exact issue.

when reading the bug description I can't tell if it's a cosmetic error or
will it affect function ?

Will it still consider it valid if its expired ? It would think not, as
that's the whole point to have an expiration date on a cert right ?

My customer has been distributing this cert across their organization since
October.  I don't think they are going to change it.  Uggg

Brian,

 

Looks like this https://tools.cisco.com/bugsearch/bug/CSCup81787 and there
is a fix in the next version.

The intermediate cert (expires in 20 yr) is loaded fine, when loading the
root cert (expires in 40 yr) it says its already expired in 1969 !

 

Is there a limit on the length of a Cert or perhaps just a bug in code ?

Anyone run into this before ?

This is the longest I've seen someone sign a cert for.  Is this common to
use such a long duration ?

I have a TAC case open, still waiting to be contacted by them.

 

 


First thought would be 32-bit UNIX time wrapping in 2038.  Pretty sure that
VCS is based on Linux.  The 20 year cert would be within that range, the 40
year one wouldn't be.  I'd be curious if both of them being 20 years
resolves it.

And I chuckled when I read it, we're going through headaches with certs and
renewals/replacements right now, and I really wish I could do 40 years on
them so I would be long gone before they expired and had to be replaced
again.  ;-)
