I find one of the easiest examples of this concept in real life is a mail box. But in order to decrypt the message the second key, which is meant to be private, is required. Anyone can use it to secure the message for the recipient. One key, used to encrypt a message for someone, is meant to be public. The basic premise of PPKE is to separate the items needed to encrypt and decrypt a message. This is a common type of encryption and is the same kind used for HTTPS. GPG is based on public/private key encryption (PPKE), also known as asymmetrical encryption. Throughout the tutorial, I will be using the command line version instead of any of the GUI options. 5 Since GPG is open source, it is freely available. This tutorial will walk us through using GnuPG (GPG), an open source implementation of the PGP standard, for email encryption.

What PGP provides is two key critical pieces of security: protection of the email message from unauthorized viewers (data confidentiality) and verification of the sender’s identity (data integrity). 4 PGP is a good tool for what it does, but it lacks many of features that make up modern secure messaging tools. The gold standard for encrypted email is OpenPGP (PGP). Without mainstream support for end-to-end encrypted emails, users are stuck using software that has not evolved since the early 90s. 3 This ended up being a lost opportunity to make encryption and data protection more mainstream: similar to the impact of WhatsApp rolling out end-to-end encryption in 2016. 1 This feature would move beyond just implementing HTTPS (encrypting traffic between a client computer and the email server) to implement end-to-end encrypted email that would protect users’ emails from even Yahoo!’s servers 2 -but it didn’t happen.

Back in 2014-about a year after Edward Snowden leaked documents on government spying-Alex Stamos was trying to make email a safer place from mass surveillance by rolling out encrypted emails for all Yahoo! users.
