Chris,

There are "real" certificates you purchase from a certificate authority and pay an annual fee. If this is https you pretty much need that or the user gets errors. By private I meant "self signed."

However, openssl has an option to create a certificate. You type the name, address, whatever, and it makes a certificate. It is JUST AS GOOD as a purchased certificate (except https or perhaps others that want certificate authority certificates). I use them for FTP and SSH and many things .

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365

You can put your own expire date(days) when you make the cert. A screen will come up and ask 20 questions :-) If you cannot do it (don't have openssl installed) I can do it for you. It certainly will work as a stop-gap. We don't need it for https as it is Apache on a machine that is hosted.

So... everything above is exactly what we do with this vendor. We don't have a problem getting a well-known-CA to sign the certificate. We have (had) a problem with the vendor just getting the damned work done.

Yes, I know it is a 5-minute process but when you are dealing with a big company where you have to have 6 managers in multiple time zones call each other to confirm the problem, have a meeting about the solution, determine a course of action, allocate a resource to perform the work, QA the solution, then get an IT review of everything before placing something into production, that 5-minute fix can take days or weeks.

I just wanted to say "I still trust this certificate, even though it has expired."

Is that possible to do without recompiling stunnel?

Thanks, -chris

Use openssl to make a private cert?

What is a "private cert"?

Also, I need to trust an existing certificate... If they can create a new certificate, then I can just trust the new one. I'm looking for a stop-gap measure, here.

Thanks, -chris

All,

Does anyone know if it is possible to perform all other verification of a client certificate EXCEPT allow the certificate to have expired?

We have a vendor whose certificate has expired, and we want to allow their old certificate to work while they chase their tails trying to figure out the best way to re-issue a new cert for us. *eyeroll*

Is it possible?

Thanks, -chris
