Modernizing RDP Certificates

This post is a small (promise!) but practical addition to my PKI series.

I wrote this blog because I wanted my own version of “how to set up RDP certificates.” Mostly as personal documentation, I can’t remember everything off the top of my head anymore… getting old.

During my initial research, I was surprised to see that many blogs still recommend older practices, SHA1 signatures, legacy cryptographic providers, or RSA 2048-bit keys without much explanation. And to be clear, I’m not saying RSA 2048 is bad. It’s absolutely still secure and widely used.

PKI – Part 2: Choosing the key length and algorithm

As I advance into the heart of PKI in this second installment, the focal point shifts towards two important decisions that anyone involved in setting up a PKI must deal with, choosing the appropriate key length and the cryptographic algorithm. These choices are far from arbitrary, for they are the foundation of a secure and efficient PKI. The selection at this stage will determine the resilience against cyber treats for the foreseeable future.
