[stunnel-users] stunnel PSK support via custome openssl engine

Dear Stunnel-users,

From Stunnel man pages, I could see that we could read PSK secret from plain text file with following option: PSKsecrets = psk.txt

Could it possible to use custom openssl engine to read PSK file from HSM. I know that this works for reading TLS keys. I am not sure how I could do it for PSK. Thanks for your support, Regards, Tarak
