Hello David,

Please reply to the list, so others are able to comment too.

I don't know the 'default certificate provided by Stunnel'.  I expect
it to be depending on the distribution.

However, if there are "BEGIN/END CERTIFICATE" lines in your file, but
no "BEGIN/END RSA PRIVATE KEY", then the file is in PEM format, but
the key is missing.  Maybe you have separate files for private key and
certificate.  If this is the case, you may either concatenate key and
certificate to a single file or specify both files in the stunnel

>> key  = my-private-key.pem
>> cert = my-certificate.pem
