This blog post discusses how to generate SSH keys and self-signed certificates using Terraform's tls_private_key resource in version 1.17. It provides detailed information about key algorithms, file permissions, and security implications of storing private keys unencrypted in the state file. The author aims to present a straightforward lab setup using two providers: hashicorp/tls for key generation and hashicorp/local for writing them to disk, without the need for cloud credentials.
