SSH public key

A quick way to set up access when we're working together on a server.

Install my key

Run this as the account I should log into. It adds my ED25519 public key, sets SSH file permissions, and skips the key if it's already installed.

BASH QUICK INSTALL

curl -fsSL https://prestonursini.com/ssh | bash

This grants me SSH access to that account. To remove access later, delete my key's line from ~/.ssh/authorized_keys.

You can also paste this key into your hosting provider's SSH key settings.

Create the directory and set its permissions.mkdir -p ~/.ssh && chmod 700 ~/.ssh
Create the authorized keys file and restrict its permissions.touch ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys
Add the public key above on its own line in ~/.ssh/authorized_keys, keeping any existing keys.
