### Introduction

`RVM` is a command-line tool that allows you to easily install, manage, and work with multiple ruby environments from interpreters to sets of gems. It was originally started in October of 2007.

Ruby Version Manager, often abbreviated as RVM, is a software platform for Unix-like operating systems designed to manage multiple installations of Ruby on the same device.

GPG stands for Gnu Privacy Guard and it is supported by the Internet Engineering Task Force ([IETF](https://www.ietf.org/)) through the [RFC 4880](https://www.ietf.org/rfc/rfc4880.txt).

The IETF publishes RFCs authored by network operators, engineers, and computer scientists to document methods, behaviors, research, or innovations applicable to the Internet.

GnuPG (more commonly known as GPG) is an implementation of a standard known as PGP (Pretty Good Privacy). It uses a system of "public" and "private" keys for the encryption and signing of messages or data.
