# generate public key file in ASCII-armor format $ gpg -export -armor MrAnderson > MrAndersonPubKey.asc # generate public key file in binary format $ gpg -export MrAnderson > myBinaryPubKey.gpg You will also need a bash terminal to interact with the software.
DMG VS PGP SIGNATURE MEANING INSTALL
You can get it on MacOS using homebrew ( brew install gpg), on Linux using any of the package managers, or on Windows by downloading the binaries directly from the GnuPG official website. There is much more to learn about privacy, encryption, and GPG than I cover in this series for information on who invented this whole thing in the first place, check out Phil Zimmermann's Wikipedia page for more on the difference between GPG and PGP, check out this article to dig deeper into the specifics of GPG, check out their docs.įirst, make sure you have GPG installed on your computer. GPG does much more, but this post is really about those two basic tasks and their related options. Verify the validity of a signature from someone else on a specific piece of data.Signing a piece of data in a way that only a person knowing a specific key could have done.Knowledge of these numbers (the keys) allows us to perform many tasks, two of which we'll tackle here: Another important aspect of cryptographic keys as used in GPG is that they come in pairs: a public key and a private key. They are often really, really big numbers, but simple integers nonetheless. One important aspect of cryptographic keys is that they are simply numbers. PGP is the protocol, and the command line tool we use to perform tasks using this protocol is called gpg. You can think of OpenPGP as email and GPG as one implementation of the email protocol (like Hotmail or Gmail). In practice, the terms GPG, OpenPGP, and PGP are often used interchangably even though they probably shouldn't be. GPG implements the OpenPGP standard maintained by the Internet Engineering Task Force.
DMG VS PGP SIGNATURE MEANING SOFTWARE
GPG stands for GNU Privacy Guard and is a small open source piece of software that allows you to manage keys for cryptographic purposes.
DMG VS PGP SIGNATURE MEANING HOW TO
Check out Part 2 for the lowdown on how to encrypt and decrypt messages. Note: this post is the first of a 2-part series aimed at developing a functional use of GPG for the day-to-day tasks of anyone who cares about software.
The goal of this article is to get you up to speed on two of the main uses of the GPG cli software: cryptographically signing and verifying signatures on data. It turns out it's rather easy, and all you need is a terminal and maybe half an hour of time! You can browse more details and other various blog posts and articles he has written onĪnyone who cares about software should learn how to produce cryptographic signatures on data (documents, messages, binaries, git commits) and how to verify other people's signatures on those types of data.
