OpenSSL offline root CA, ADCS as Intermediate CA, and for fun, GitHub + Azure Static Website to host the CRLs :p

Microsoft Tunnel and EAP-TLS posts in the works :)

@nathanmcnulty I end up using portable xCA quite often for internal CA stuff. The whole gui and the database can all live on removable media.

@interpipes That's pretty cool! I thought about using Smallstep for my example.

We didn't have an HSM, so we did OpenSSL on an encrypted removable drive (a couple actually, one offsite backup and one on-site in a fire safe).

The hope is you only have to use it once or twice during your lifetime, lol
