How to configure Certificate Authority on Ubuntu/Debian
A Certificate Authority plays a vital role in ensuring and verifying secure connections between clients and servers. When you try to connect to a remote server – let’s say a website, for example – how does your system know that it is connecting to the right place? After all, there is nothing stopping any rogue system from claiming itself as a website which it is actually not. This is where certificate authority servers come into play, by helping our client system verify that we are connecting to the intended server. This particular example is in the context of a website connection, so would involve the HTTPS protocol, but certificate authorities can also be used to authenticate other types of connections, such as VPN.
Step-by-Step Guide: Adding Certificates to Ubuntu’s Trusted Authorities
In today’s digital landscape, we must be careful to authenticate our network connections to remote servers. To help keep us secure, we use certificates that allow us to verify connections between clients and servers. A Certificate Authority is a crucial part of this process, as it is responsible for issuing the certificates to clients and servers, and verifying the devices that are trying to establish secure connections to each other.
How to check GPIO status
The GPIO (General Purpose Input/Output) pins of the Raspberry Pi are how the device can interface with external hardware components. It is how things like sensors and actuators plug into the Raspberry Pi, and allow users to control such devices from the Raspberry Pi itself. Something as simple as turning an LED on or off will require setting the pin to which it is plugged in to either true or false, which changes the current status of that pin.
Raspberry Pi as Music Streamer
Thanks to its small size and simple requirements, the Raspberry Pi can be transformed into a variety of different specialized devices. One such role that it can fill is that of a dedicated music streamer, or jukebox. Whether you have your own music files (MP3, FLAC, etc) already downloaded and want to stream them to speakers around the house, or you rely on streaming services like Spotify or Pandora, utilizing the Raspberry Pi as a music streamer is a great way to enjoy some tunes. In this tutorial, we will go over the step by step instructions to help you turn your Raspberry Pi into the ideal music streaming device.
