SSH Key Wizard

SSH Key Wizard.md

Simple batch script to easily create a SSH key pair and append the public one to the authorized_key file in your local Linux server. Use > to overwrite that file, or >> to append the key to it (default).

It will provide a one-line command to access your server without a password, just copy it and add it to a new profile in Windows Terminal for easy access.
