Is there any good #book/ #workshop which explains things one need to write/develop to create own #certificate #authority application? For learning purpose. #x509 #PKI

This is more of a security question, but I currently know way more people on ruby.social than infosec.exchange. I want to use a #Yubikey for #SMIME or #GPG signing on #iOS & #iPadOS, but can't find:

1. Any documentation about how to integrate it with Apple Mail.

2. Anyplace that offers #x509 certificates for S/MIME at zero or minimal cost the way @letsencrypt offers free #SSL certs.

Self-signed S/MIME certs are a non-starter, and there are no full-featured #OpenPGP apps on iOS. Suggestions?

Let's Encrypt will issue new intermediate certs in Q1/2024: https://groups.google.com/a/mozilla.org/g/dev-security-policy/c/L7XoAXt_s1c

Make sure your LE cert deployment logic includes serving the right intermediates that ACME should hand you, not just that same old LE intermediate you got years ago. Otherwise, there'll be breakage...
