[stunnel-users] Certificate management

[Koenraad Lelong]

Hi,
Since a few months I'm playing with stunnel.
Last month I installed a stunnel at a customer. This week he reported he 
could not connect any more. After testing here I discovered the CA cert 
had expired. I made this myself and I didn't see that it's only valid 
for one month. I made new certificates making sure they are valid for 
longer than one month, so this is solved for now.
My question : are there good documents about management of certificates 
? I'm specially interested in renewing the certificates.
Regards,
Koenraad Lelong.
