[openssl-users] PSK generation for TLS 1.3

Hi All,
Can anyone provide me pointers on how can we generate external PSK to be
used inTLS 1.3.

When I save a a session using SSL_CTX_sess_set_new_cb(), it provides an
in-band PSK for next resumption connection.
I use PEM_write_bio_SSL_SESSION to save the session.

How do we use PSK externally. Can I use the same session file which was
saved during in-band connection. I believe in case of an external PSK, both
client and server should have a copy in advance.

Best Regards,
