Is GPG Still Useful In Today’s Insecure World?

Reading Time: 5 minutes

Introduction

In this article, we will be exploring GnuPG or GPG as it is more commonly known. We will discuss if this software platform is still needed, if it will still be useful in the future, and how to install and utilize it. 

GnuPG is a free, open-source command-line tool and application to apply the OpenPGP standards to secure information. GPG itself is distinct from the OpenPGP standard because it uses that protocol to define the canonical format used to encrypt messages, certificates, and signatures via a public keys exchange.

Why do I Need to Install or Reinstall My SSL Certificate?

According to Globalsign;

The Certificate Authority (CA) industry was alerted of compliance implications related to the inclusion of a specific extension (OCSP-signing extended key usage) in CA certificates which has, under certain conditions, unintended compliance and security implications. A number of GlobalSign Issuing CAs have been impacted by this issue. While no key compromise or security incident has taken place, we will be revoking these Issuing CA’s as part of our remediation plan in accordance with the CA/B Forum Baseline Requirements and the GlobalSign CPS. Revoked intermediate certificates can cause errors in the validation of certificates signed by these Intermediate Certificates.

How to Share Encrypted Information

Reading Time: 6 minutes

This article will discuss the methods to send information securely over email using GPG/PGP as the main encryption tool. The difference between PGP and GPG is mainly that PGP is a proprietary solution controlled by Symantec, and GPG is the open-source standard that is defined by RFC 4880. Functionally, each format is virtually identical due to GPG being the offspring of the original PGP standard. Because there are numerous email clients, specific GPG settings will vary. For this tutorial, we will use Gmail and Thunderbird as examples.
