A public key can be shared, but a private key should never-ever be shared. A private key is the key that allows you to decrypt the messages sent to you based on your public key, the private key can also be used to generate message and file signatures. A public key is the key that other people use to encrypt a message that only you can open. ![]() The usability of PGP depends on the public/private key pair encryption schematic.Įvery PGP user has both a public and private key. When someone says PGP, it is generally safe to assume that they are referring to the OpenPGP standard. GPG: GNU Privacy Guard, another popular solution that follows OpenPGP standards.OpenPGP: Pretty Good Privacy, but it is an open-source version, and it has become the universally-accepted PGP standard.PGP: Pretty Good Privacy, original proprietary protocol.There are different variations of PGP: OpenPGP, PGP and GPG, but they generally all do the same thing. You may find yourself needing to use PGP if you want to be certain that only the intended receiver can access your private message, thwarting the efforts of intercepting parties, or if you just want to verify the sender’s identity. PGP is primarily used for encrypting communications at the Application layer, typically used for one-on-one encrypted messaging. PGP is a protocol used for encrypting, decrypting and signing messages or files using a key pair. With that caveat in mind, let’s jump straight in. Clients & Use Guides: Windows, Linux, Mac, Web.Availability: key servers, web of trust, metadata.Integrity: message/file authenticity, web of trust.Confidentiality: message encryption, information storage.To mitigate any identified threats and reduce risk, we implement operational security practices.Īt a more concise glance, we will discuss the following: ![]() Next, we get familiar with our threat model (similar to OPSEC Model) in this step, we analyze personalized risks and threats. To better understand our security stance, we assess the CIA Triad, a theoretical Information Security model, that considers the confidentiality, integrity, and availability of information. The goal of this introduction to PGP is to illustrate a more timeless and operational approach to using PGP safely, with respect to both information security and operational security.įirstly, we introduce PGP theoretically and practically, this means understanding how PGP works and what we can actually do with PGP. Most generic guides simply explain PGP at a high-level or how to encrypt and decrypt messages using specific software, and not much more than that. PGP is a popular solution for encrypting, decrypting, signing, and verifying messages and files, often found in email communications and package repository identity verification ( because security matters). If you don’t already know what Pretty Good Privacy (PGP) is you may have heard of PGP before, perhaps during a discussion on how to secure your communications, or perhaps in one of those how-to maintain privacy guides.
