+
+# google\_compute\_region\_ssl\_certificate
+
+Get info about a Region Google Compute SSL Certificate from its name.
+
+## Example Usage
+
+```tf
+data "google_compute_region_ssl_certificate" "my_cert" {
+  name = "my-cert"
+}
+
+output "certificate" {
+  value = data.google_compute_region_ssl_certificate.my_cert.certificate
+}
+
+output "certificate_id" {
+  value = data.google_compute_region_ssl_certificate.my_cert.certificate_id
+}
+
+output "self_link" {
+  value = data.google_compute_region_ssl_certificate.my_cert.self_link
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` (Required) - The name of the certificate.
+
+- - -
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+* `region` - (Optional) The region in which the resource belongs. If it
+    is not provided, the provider region is used.
+
+## Attributes Reference
+
+See [google_compute_region_ssl_certificate](https://www.terraform.io/docs/providers/google/r/compute_region_ssl_certificate.html) resource for details of the available attributes.
