Managing server certificates

Getting information about a server certificate

You can get information about your server certificate, such as when it expires or what level of encryption it provides.

Console

1. Go to the Cloud SQL Instances page in the Google Cloud Console.

   Go to the Cloud SQL Instances page

2. Click the instance name to open its Instance details page.
3. Click the Connections link in the left navigation pane.
4. Scroll down to the Configure SSL server certificates section.

   You can see the expiration date of your server certificate in the table.

   To see the certificate type, use the gcloud beta sql ssl server-ca-certs list --instance=[INSTANCE_NAME] command.

gcloud

gcloud beta sql ssl server-ca-certs list --instance=[INSTANCE_NAME]

REST v1beta4

You can see details about the server certificate when you describe your instance:

Before using any of the request data below, make the following replacements:

• project-id: The project ID
• instance-id: The instance ID

HTTP method and URL:

GET https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id?fields=serverCaCert

To send your request, expand one of these options:

curl (Linux, macOS, or Cloud Shell)

Note: The command below assumes that you have used either gcloud init or gcloud auth login to authenticate gcloud with your user account. You can check the currently active account by executing gcloud auth list.

Execute the following command:

curl -X GET \
-H "Authorization: Bearer "$(gcloud auth print-access-token) \
https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id?fields=serverCaCert

PowerShell (Windows)

Note: The command below assumes that you have used either gcloud init or gcloud auth login to authenticate gcloud with your user account. You can check the currently active account by executing gcloud auth list.

Execute the following command:

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
  -Method GET `
  -Headers $headers `
  -Uri "https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id?fields=serverCaCert" | Select-Object -Expand Content

You should receive a JSON response similar to the following:

Response

{
  "serverCaCert":
  {
    "kind": "sql#sslCert",
    "certSerialNumber": "cert-serial-number",
    "cert": "cert-value-",
    "commonName": "ca-server-name",
    "sha1Fingerprint": "sha1Fingerprint",
    "instance": "instance-id",
    "createTime": "2020-02-10T17:18:54.935Z",
    "expirationTime": "2030-02-07T17:19:54.935Z"
  }
}

Resetting the SSL/TLS configuration

You can completely reset your SSL/TLS configuration.

Caution: Performing this action removes the ability to connect to your instance using SSL/TLS until you create new client certificates to replace any that were previously in use.

Console

1. Go to the Cloud SQL Instances page in the Google Cloud Console.

   Go to the Cloud SQL Instances page

2. Click the instance name to open its Instance details page.
3. Click the Connections link in the left navigation pane.
4. Scroll down to the Reset SSL configuration section.
5. Click RESET SSL CONFIGURATION.

gcloud

1. Refresh the certificate:

   gcloud sql instances reset-ssl-config [INSTANCE_NAME]
