Despite the appearance of a number of good privacy-focused webmail services, Pretty Good Privacy (PGP) remains the gold standard of email encryption. In this guide, we show you how to use PGP on Mac, explain how it works and how secure PGP really is.

PGP does have a number of issues (discussed below), but it is still the most widely used email encryption system, and therefore the most interoperable with others no matter which platform or email service they use.
It can also be used for signing and encrypting all sorts of other stuff but is mainly used to secure emails.
Oct 11, 2013. Nov 09, 2017 The goal of this project is to create a GnuPG front end for Mac OS X. To that extent, it will make installing GnuPG on OS X easier and provide inter application services to access GPG. Also, GPGME wrapper in ObjC will be done.

The details of how PGP works are, to be honest, rather complicated. https://evermoves169.weebly.com/blog/illusion-ghost-killer-mac-download. The important thing to remember, however, is that PGP uses public-key cryptography.
Each user has a private key which they keep secret and use to decrypt emails sent to them using their public key. They also have a public key, which they freely so that other people can use it to send them encrypted emails. Can mac os x sierra read ntfs external drive.
For this tutorial, we’ll stick to how to use PGP for encrypting emails, but PGP keypairs are also very useful for signing and verifying digital signatures.
PGP vs OpenPGP
When discussing PGP these days we almost always mean OpenPGP. This is an open-source 100% compatible clone of the original PGP, which is now closed-source software owned by Symantec.

When PGP is used to secure emails, the metadata - such as email addresses of both the sender and recipient, date and time of sending, and e-mail’s subject line - is not encrypted. Just the body text and any attachments.
Another problem with PGP is that it does not use Perfect Forward Secrecy (PFS). So once keys for one encrypted email are broken, all other emails encrypted using the same keys will also be compromised.
Arguably the biggest problem with PGP, though, is that it's just not very easy to use, with the result being that most people simply don’t. To combat this, we will show you the two easiest ways to use PGP on your Mac:
Method 1: Malivelope
Mailvelope is a free and open-source browser extension for Chrome and Firefox that makes using PGP on your Mac about as easy as PGP is ever likely to get. Please check out our full Mailvelope How-to guide for a detailed look at how it works.
Method 2: GPGTools with GPG Mail
The most common implementation of OpenPGP is Privacy Guard (also known as GnuPG or just GPG). GPG on its own is a basic command-line tool, but GPGTools for macOS provides a GUI interface and advanced features.

It is worth noting that in 2018 GPGTools make headlines due its vulnerability to the EFAIL attack which affected all versions of PGP at the time. Since GPGTools 2018.2, however, this vulnerability has been patched.
GPGTools is free, but the GPG Mail plugin for Apple Mail is designed to help fund the open-source project and costs $22. This is a one-off fee, but you do need to pay again for new versions as they are released.
