NGINX Configuration for Shared Partitions (TLS-PSK)

Question

I have a very limited battery-powered device that does not have the power to exchange keys, so instead we want to use PSK (pre-shared keys) to protect the channel. I cannot find any information on how to configure this using NGINX.

I see that ssl_ciphers has a PSK (which I included), but where / how to specify shared keys between NGINX and the client? Is it supported?

Answer 1

Nginx does not currently support PSK ciphers. There is an attempt to add support, although some preliminary fixes can be found here:
