__Gnu Privacy Guard (GnuPG)__ is a free software implementation of the [OpenPGP Standard](https://www.openpgp.org/about/standard/). Most people use GnuPG or GPG to encrypt and sign files and messages while some also use it for Secure Shell (SSH) authentication and signing their Git commits and tags.

## Installation
|
||
|
|
|
||
|
|
### Linux
|
||
|
|
GnuPG is part of Debian. To install on Debian or its derivatives:
|
||
|
|
```text
|
||
|
|
sudo apt install gnupg
|
||
|
|
```
|
||
|
|
For non-Debian Linux distributions, consult the appropriate guide for the distro of your choice.
|
||
|
|
|
||
|
|
### macOS
|
||
|
|
To install GnuPG on a Mac, you can use [Homebrew](https://brew.sh):
|
||
|
|
```text
|
||
|
|
brew install gnupg
|
||
|
|
```
|
||
|
|
|
||
|
|
### Windows
|
||
|
|
To install GnuPG on Windows, you can download the [Gpg4win Installer](https://gpg4win.org/download.html).
|
||
|
|
|
||
|
|
## Generating keys
|
||
|
|
Before you can start using GPG, you need to first generate a key pair. To do so, key in the command in your terminal or command prompt:
|
||
|
|
```text
|
||
|
|
gpg --gen-key
|
||
|
|
```
|
||
|
|
Follow the prompts by entering your name, email, and passphrase and you are done. Congratulations!
