Would libfaketime or run_as_date help?

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
