About Bitcoin security : TRUSTLESS PRIVATE MESSAGING WITH PUBLIC AND PRIVATE KEY CRYPTOGRAPHY

As a Bitcoiner, you will require a safe method for conveying secretly, without depending on an organization to scramble your information for you. For instance, unreservedly accessible strategies with start to finish encryption like Telegram (not with its default choice) and Signal and others are not difficult to utilize, yet I don’t totally trust them.

This article will tell you the best way to send messages utilizing free open-source programming, GNU Privacy Guard (gpg), which permits encryption and unscrambling utilizing public and private key cryptography. It’s more interesting at first to DIY, however when you get its hang, it isn’t so difficult. I’ll make you through it stride by step, simply track and bookmark this article for future reference. This is a little more background about gpg for the individuals who wish to burrow further. It’s important to take note of that public and private key cryptography isn’t just utilized for encryption and unscrambling, yet additionally utilized for the confirmation of advanced marks — utilized in Bitcoin exchanges and furthermore information overall (e.g., checking assuming the product you downloaded is veritable and not altered)

HOW IT WORKS ?

To make a public and private key pair, your PC produces an exceptionally huge (“unguessable”) arbitrary number from which the gpg programming will make for us a private key, and from that, a public key is made (very much like Bitcoin private keys, more information here).

The public key is imparted to the world (like a Bitcoin address) and contains your ID (email and name) which you distribute online. Here is mine. Think about the public key like an open safe. Anybody can compose a message and encode that message with your PUBLIC key (i.e., put it in your safe and lock the entryway shut) — just you have the private key and, thusly, no one but you can open your safe (i.e., decode and read the message).
