Public Key Infrastructure (PKI) – Introduction

A public-key infrastructure (PKI) is a set of roles, policies, hardware, software and procedures needed to create, manage, distribute, use, store and revoke digital certificates and manage public-key encryption. The algorithms are based on Publick-key cryptography. The format of the digital certificate is defined in X.509 standard.  Certificate Authority – CA digitally signs and publishes … Read morePublic Key Infrastructure (PKI) – Introduction

Cryptography basics 2 of 2

My previous post outlines several core concepts around cryptography, such as asymmetric key encryption, digital certificate, the encoding formats and relevant file extensions. In this article, we continue to explore cryptography use cases, where these concepts are connected and put into application. The most important use case is TLS handshake. I cannot stress enough how … Read moreCryptography basics 2 of 2
