terraform-rsa-encrypt Latest Release

README Header

Cloud Posse

The terraform-shell-rsa-encrypt module can be used for encrypting content using an RSA public key. It is the missing part of the built-in "rsadecrypt".


This project is part of our comprehensive "SweetOps" approach towards DevOps.

Terraform Open Source Modules

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

Here's how to invoke this example module in your projects

module "encrypt" {
  source = "zeroae/rsa-encrypt/shell"

  public_key_pem = file("path/to/public-key.pem")
  content_base64 = filebase64("path/to/sensitive.txt")
}

Examples

Here is an example of using this module:

Makefile Targets

Available targets:

  help                                Help screen
  help/all                            Display help for all targets
  help/short                          This help short screen
  lint                                Lint terraform code
