No description provided.

This module should behave similarly than the kms module (except for resource creation). In particular, it should support multiple keys per key ring, and have the same output as the kms module.

[ftchawe-aneo]

The documentation should highlight the purpose of the module in the framework of ArmoniK

I am not a big fan of the name of the module. I would prefer to have kms at the beginning of the name.

Here are some name suggestions (in order of personal preference):

• kms-get
• kms-data
• kms-existing
• kms-import
• kms-external

Suggested change

	type = list(string)
	type = set(string)

[lemaitre-aneo]

Suggested change

	output "my_crypto_key_output" {
	output "cyprto_keys" {

[lemaitre-aneo]

There is a missing output compared to to the resource module:

output "crypto_key_ids" {
  description = "The Map of the created crypto keys."
  value       = { for key, value in google_kms_crypto_key.keys : key => value.id }
}
