Generate Fernet key using Terraform

Fernet keys can be generated using Python or OpenSSL, but what if you want to manage the key as part of your infra in Terraform/OpenTofu?

resource "random_password" "fernet" {
  length = 32
}

resource "azurerm_key_vault_secret" "fernet" {

  value = base64encode(random_password.fernet.result)

  name  = "fernet-key"
  key_vault_id = azurerm_key_vault.key_vault.id
}
