This article is part of the Admin Setup (Step-by-Step) guide.
SSH is a means to securely access remote servers, such as the one you'll be setting up on DigitalOcean to host your wallets and admin.
Like cryptocurrency wallets, SSH uses cryptographic public and private keypairs.
Your public SSH key is what you'll provide DigitalOcean in order to authorise access to your server. Your private key remains on your computer and is required to log into your server.
Create a SSH keypair by following the directions below based on your computer's operating system.
Linux or Mac OS
Follow the directions found here: How to Create SSH Keys with OpenSSH on Linux or macOS
If using Windows, download and run the 64-bit MSI installer from the PuTTY website.
Then follow the directions here: How to Create SSH Keys with PuTTY on Windows
Your public key
Copy the public key portion to a text file, as we'll use it when creating a DigitalOcean droplet.
