Use stunnel in inetd mode. Execute a script (or better C program). Copy the certificates for making the stunnel connection to a directory that is OK … then delete them immediately after stunnel starts. Hack – but might be OK for what you are doing. I am not sure why anyone would think it more secure to put the keys into the stunnel command than to just use them from a file … but I likely do not know enough about your application to make a judgement.

Is there a way to specify the actual certificate content in stunnel configuration (similar to other parameters like port numbers etc.,) so that the same can be leveraged.
