Sharing some thoughts after staring at some home packet captures. OCSP is as bad for privacy as plain text SNI blog.seanmcelroy.com/2019/01/0

Burp Suite and Frédéric Chopin are an amazing rainy day Wednesday combination.

Shoot holes, I'm curious to hear your thoughts.

A few things about this:

1. No certificate transparency, but since that's to keep CA's honest, seems superfluous in this setup
2. Requires client-side DNSSEC and DANE validation, but we should have that anyway
3. No revocation possible, but if since clients could validate domains on their own with DNSSEC and DANE, and if validity periods were short, does it really matter?

So, infosec.exchange, seems like infosec social media is done with EV and commercial CA's, but praises Let's Encrypt. But, why do we even need an intermediary if all they do is DV? Seems like the plumbing is there to remove 3rd party assertions and trust if encryption is the objective:

1. Generate pub/priv keypair
2. Create X.509 cert (maybe a max validity of 7 days or something short)
3. Sign it with priv keypair
4. Enable DNSSEC (I know, I know)
5. Publish DANE TLSA record matching cert

I could stand to learn much more about lattice based crypto. Bookmarking this for later: intensecrypto.org/public/
