+# huaweicloud_rds_ssl_cert_download_links
+
+Use this data source to get the list of RDS instance SSL certificates.
+
+## Example Usage
+
+```hcl
+data "huaweicloud_rds_ssl_cert_download_links" "test" {}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `instance_id` - (Required, String) Specifies the ID of RDS instance.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `cert_info_list` - Indicates the list of certificates.
+
+  The [cert_info_list](#cert_info_list_struct) structure is documented below.
+
+<a name="cert_info_list_struct"></a>
+The `cert_info_list` block supports:
+
+* `download_link` - Indicates the download link of certificate.
+
+* `category` - Indicates the category of certificate.
+  The value can be: **international**, **national**.
