Most people who use email know it is not very secure. It’s been compared to mailing someone a postcard. Meaning anyone who gets a hold of it can read it. Yesterday we covered using Mailvelope to encrypt emails using PGP. Today we discuss Bitmessage.
Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide “non-content” data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.
You can use Bitmessage for direct contact or use it for the equivalent of an email list that they call “channels”.
Mailvelope is a Firefox plugin to add PGP encryption to any webmail provider. PGP stand for Pretty Good Privacy and is a standard means of public key cryptography. This plugin allows you to use it without the need for using an email client.
You can also use Mailvelope to encrypt files.
When you visit a common webmail provider you will see the Mailvelope icon in the compose box:
This will open the Mailvelope editor to compose message in. The reason is to secure it from the email provider prior to encryption.
Everyone nowadays uses some sort of ad-blocking plugin in their browser. But the issue with many is they use up local system resources blocking the ads. Making everything slower, which is counterproductive. A more efficient and cleaner way is to get yourself a Raspberry Pi and install Pi-Hole on it.
A Raspberry Pi is a small very affordable computer sold for hobbyist, teaching, and projects. There are a lot of fun projects that can be done with them.
Now that you have your card loaded you can enter the boot partition of the card and add an empty file named “ssh” (no extension). This will enable SSH when you boot the card in the Raspberry Pi. Once done with this step eject your card and insert it in the Raspberry Pi. Plug in the Cat-5 cable to your router and plug in the power (micro-usb) cable last. You will see it booting up with lights flashing. After a few minutes check your router to see what IP address the Raspberry Pi listed in the web interface. Everyone’s routers are different so going into that is beyond the realm of this howto. Searching should get you any info you need on this.
