# Default SSH Key
|
|
|
|
Create a default `id_rsa` SSH key if one is not present in the repository / fork of Install Doctor
|
|
|
|
## Overview
|
|
|
|
This script generates a pair of default `id_rsa` and `id_rsa.pub` keys if one is not already present
|
|
on the system after the Install Doctor provisioning process completes. It also ensures the private
|
|
key is only readable and writable the provisioning user.
|
|
|
|
|

|
|

### Ensure id_rsa is present and create one if it does not exist
|
|
if [ ! -f "$HOME/.ssh/id_rsa" ]; then
|
|
logg 'Generating missing default private key / public key (`~/.ssh/id_rsa`)'
|
|
ssh-keygen -b 4096 -t rsa -f "$HOME/.ssh/id_rsa" -q -N ""
|
|
chmod 600 "$HOME/.ssh/id_rsa"
|
|
fi
|
|
```
