Terraform CLI and Terraform AWS Provider Version

Terraform v1.0.0
on darwin_amd64
+ provider registry.terraform.io/hashicorp/aws v3.54.0

Affected Resource(s)

• aws_kms_public_key

Terraform Configuration Files

resource "aws_kms_key" "key" {
  description              = "My Key"
  deletion_window_in_days  = 30
  key_usage                = "SIGN_VERIFY"
  customer_master_key_spec = "RSA_2048"
}

data "aws_kms_public_key" "key" {
  depends_on = [aws_kms_key.key]
  key_id = aws_kms_key.key.arn
}

output "public_key" {
  value = {
    public_key = data.aws_kms_public_key.key.public_key
    algs = data.aws_kms_public_key.key.signing_algorithms
    usage = data.aws_kms_public_key.key.key_usage
  }
}

Expected Behavior

According to the docs the public_key attribute should have returned the base64 encoded DER public key as received in the PublicKey attribute returned by the API call.

Actual Behavior

The public_key attribute returns a binary value, which doesn't even seem to be the raw DER, as if I base64encode it, it still isn't the correct value :-(

I have compared with the output of aws kms get-public-key --key-id <key-id> and by viewing the public key in the AWS console.

All other attributes returned by this data source seem to be correct.

Steps to Reproduce

1. terraform apply
