Manage server CA certificates

Get information about a server CA certificate

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

Console

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Select Connections from the SQL navigation menu.
4. Select the Security tab.

   In Manage server CA certificates, you can see the expiration date of your server CA 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 v1

When you describe your instance, you can see details about the server CA certificate:

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

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

HTTP method and URL:

GET https://sqladmin.googleapis.com/v1/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 following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Execute the following command:

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id?fields=serverCaCert"

PowerShell (Windows)

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running 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://sqladmin.googleapis.com/v1/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-",

    "expirationTime": "2030-02-07T17:19:54.935Z"
  }
}

Reset 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. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Select Connections from the SQL navigation menu.
4. Go to the Reset SSL configuration section.
5. Click Reset SSL Configuration.
