Ask HN: Hands-on/practical data security and crypto key short course?

I'm a platform/security engineer. I do a lot of preaching on how standardized data encryption + crypto key management could work and how it could simplify platform engineer's life by not having to configure access/permission policies for every single data platforms and then figure out how to align these policies on various platforms. I was wondering if this is something that will be interesting to people where I can walk through the end to end process from creating a key, configure key access, adding it to the client, encrypt the data etc. show how different types of crypto keys could be applicable in different scenarios. I thought I could maybe just create 30 mins course w/ some terraform + data encryption code step by step. Will this be something people are interested?
