Can you do end-to-end encryption without an app like Signal or Whatsapp? This video will teach you about GPG (GNU Privacy Guard – which is an Open source implementation of PGP) and you will learn how to use the Public Key infrastructure to encrypt anything end to end, even while you post in social media, private messages, and email. There’s no limit to where this can be used. This will explain the use of GPG in a simple way, without command line instructions, or even requiring the use of a specific app and a clear explanation of how it works without the technical jargon.
