PSK only makes sense for svelte SSL libraries that either run
on devices with too little CPU to do public key crypto, or don't
want to the pay the code footprint of X.509 certificate processing.

For OpenSSL on a typical computer, PSK deployment and application
support is more complex than just going with self-signed certs.

The OP is IMHO better off avoiding PSKs.
