To get the KMS keys in an account and Region

The following list-keys example gets the KMS keys in an account and Region. This command returns both Amazon managed keys and customer managed keys.

aws kms list-keys

Output:

{
    "Keys": [
        {
            "KeyArn": "arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab",
            "KeyId": "1234abcd-12ab-34cd-56ef-1234567890ab"
        },
        {
            "KeyArn": "arn:aws:kms:us-west-2:111122223333:key/0987dcba-09fe-87dc-65ba-ab0987654321",
            "KeyId": "0987dcba-09fe-87dc-65ba-ab0987654321"
        },
        {
            "KeyArn": "arn:aws:kms:us-east-2:111122223333:key/1a2b3c4d-5e6f-1a2b-3c4d-5e6f1a2b3c4d",
