Assume I have already an *.pem cert (for SMTP over STARTTLS transfer). Where (in whcih directory) should I put this cert file? Ben On Fri, 18 Oct 2013 12:35:25 +0000, Eckert, Doug wrote:

You can use OpenSSL to convert between formats (to .pem for STunnel)

You can also use openssl to strip the key's passphrase. This is handy for automatic starting (init/cron/at) of STunnel without having it prompt for the passphrase.

$ openssl rsa -in source.pem -out target.pem

Which X.509 certificate types (e.g. .crt, .pem, .der .p7c) are possible for stunnel?

Assume I have got such a certificate as separate file (and not retrieved by OpenSSL).

How do I import it into stunnel?

Do I have to just copy it into (which ?) directory?

Does the certifcate file name have to have a certain pattern? Or is stunnel smart enough to read and analyze the content independently from filename?

Thank you Ben
