is there anyone who's familiar with security stuff (dtls handshake, in particular) ideally with bouncycastle but any JCA knowledge would be helpful? i'm trying to navigate all these classes and getting lost amidst everything and could really use some guidance. i get this isn't exactly kotlin-specific but i'm getting desperate.

I wrote this a long time ago but maybe it still has something useful. http://blog.palominolabs.com/2011/10/18/java-2-way-tlsssl-client-certificates-and-pkcs12-vs-jks-keystores/index.html

thanks marshall, i'll give that a read. it looks like i may have stumbled onto the answer as to what was blocking me, but i feel as confused about this stuff as ever
