![]() ![]() ![]() You will use GPG to manage all the public keys for the security teams you regularly communicate with. It’s an essential but necessary evil.Īs a security researcher, you will converse with many security triage teams throughout your career. So GNU Privacy Guard provides a complete key management system for you that you will learn to love (or love to hate). You will find installable packages for pretty much every platform you will use, is available for free, and integrates well with hardware smartcards and Yubikeys. Whatever it’s called… just stick with using GPG. I think last I heard, it’s called Symantec Encryption Desktop, but it’s owned by Broadcom because they own the controlling stake in Symantec’s enterprise security business. PGP has a long checkered history as it has changed hands with different commercial entities over the years. GPG leads some people to believe they are the same thing. GPG can provide digital encryption, signing, and key exchange and is interoperable with modern versions of PGP.Īnd here lies the first bit of confusion. ![]() GPG relies on the OpenPGP standard ( RFC-4880), an open-source implementation of Phil Zimmermann’s work with Pretty Good Privacy ( PGP). This allows you to securely transmit information between parties that can be used to ensure the information is genuine and only accessible by authorized parties. GNU Privacy Guard, better known as GnuPG or just GPG, is an implementation of public key cryptography. Let’s get to it! What is GPG and why is it important for security researchers I hope to change that with this article.īy the end, you will understand how to protect sensitive data and easily encrypt messages that can only be accepted by the intended recipient, preventing other parties from weaponizing your findings. It’s clear that some security researchers don’t know how to use public-key cryptography. Several community members contacted me through emails, Slack, and Discord messages with varying questions about my comments on digitally signing reports and encrypting exploits to ensure they didn’t fall into the wrong hands. A few weeks back, I wrote an article about why writing exploits for vulnerabilities you find in APIs is important. ![]()
