PKI – Part 6: Demystifying the CAPolicy.inf file

Ever heard of the capolicy.inf file? It’s like a digital instruction manual for a Certificate Authority (CA) server. It pre-configures the CA and has a say in how certificates are set up or renewed. In other words, it’s a behind-the-scenes helper that ensures everything is governed with digital certificates. In this blog post, I’ll break down what this file does and why it matters in plain and simple terms.

PKI – Part 4: Understanding Cryptographic Providers

Introduction

In the realm of Public Key Infrastructure (PKI), where the keys to digital security are exchanged, stored, and safeguarded, cryptographic providers play a pivotal role. These providers are the guardians of cryptographic keys, ensuring the integrity, confidentiality, and authenticity of digital communications.

The basics on Diffie-Hellman key exchange.

Do you want to know a secret? You probably do, question is, would you like it if anyone else knew your secret as well? I am guessing not. That is why, on the Internet, we use encryption for the data that we send and receive, just to make sure that someone else is not listening in on our conversation. Encryption is not only used when directly communicating with each other, it is also used for something we call “integrity”, a.k.a. “I want to make sure that I get what the other end is sending without anyone modifying it in transit”. So, use encryption anywhere! read on while we explore the basics on how data is securely transferred from one place to another using Diffie-Hellman key exchange.
