I'd like to build a ktor server that uses the embedded Netty engine, exposes an SSL endpoint, and validates client certificates against a custom CA. Serving over SSL is easy and fun thanks to the magic of ktor, but I'm struggling with validating client certificates. I can see in https://github.com/ktorio/ktor/blob/master/ktor-server/ktor-server-netty/src/io/ktor/server/netty/NettyChannelInitializer.kt#L47 that the NettyChannelInitializer uses the familiar SslContextBuilder from Netty. I think that calling clientAuth and trustManager on the SslContextBuilder instance would do what I want. My problem is that I can't see how to pass settings into my engine config to make NettyChannelInitializer do what I want. Any ideas? Or is this not possible in the current version of ktor, and I should use nginx as a reverse proxy?

I don’t think there is out of the box access to SslContextBuilder right now. Please submit an issue to GitHub, we’ll discuss what we can do for you.
