# Generate Missing Public SSH Keys
|
|
|
|
Attempts to create missing public SSH keys for all private keys that are missing a public key file
|
|
|
|
## Overview
|
|
|
|
Using private SSH keys, you can generate the corresponding public key. This script ensures that any SSH private key
|
|
that does not have a matching `.pub` public key file has one generated.
|
|
|
|
|
|
|
|
