+     * Identifies an asymmetric KMS key. KMS uses the private key in the asymmetric KMS key to sign the message. The
+     * `KeyUsage` type of the KMS key must be `SIGN_VERIFY`. To find the `KeyUsage` of a KMS key, use the DescribeKey
+     * operation.
+     *
+     * To specify a KMS key, use its key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix it with
+     * `"alias/"`. To specify a KMS key in a different Amazon Web Services account, you must use the key ARN or alias ARN.
+     *
+     * For example:
+     *
+     * - Key ID: `1234abcd-12ab-34cd-56ef-1234567890ab`
+     * - Key ARN: `arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab`
+     * - Alias name: `alias/ExampleAlias`
+     * - Alias ARN: `arn:aws:kms:us-east-2:111122223333:alias/ExampleAlias`
+     *
+     * To get the key ID and key ARN for a KMS key, use ListKeys or DescribeKey. To get the alias name and alias ARN, use
+     * ListAliases.
