Encryption, a process in which digital messages are scrambled so they can’t be accessed by anyone other than those they are meant for, it is a means to ensure freedom of expression and to keep information secure in the digital world. Pretty Good Privacy (PGP) is one of the most widely used encryption and decryption techniques. It can be used on relatively low-end personal computers, while maintaining almost unbreakable encryption levels. Experienced readers already know that PGP is essential to survive the DarkNet scene and is extremely popular in the cryptocurrency world. It operates across a number of different standards, the most popular of which is the open source OpenPGP standard. You can use this system for free to send private communications through any channel including emails, instant messaging services, chats and private messages on forums or other websites. Public keys are used to encrypt messages to specific recipients. Private keys on the other hand are used for decrypting messages. Once downloaded, all you need in order to send a message using PGP is the public key of the person you want to send it to. The increasing amount of data we’re all generating is everywhere: Smartphones get stolen, thumb drives get lost, email passwords get leaked, cloud servers get breached, WiFi networks get tapped, Encryption is your last line of defense, the one thing that can protect your data when all else goes wrong.
