#!/bin/bash

# generate new personal ed25519 ssh keys
ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "rob thijssen <rthijssen@gmail.com>"
ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_robtn -C "rob thijssen <rob@rob.tn>"

# generate new host cert authority (host_ca) ed25519 ssh key
# used for signing host keys and creating host certs
ssh-keygen -t ed25519 -f manta_host_ca -C manta.network
