# Configure Self-Managed Certificates

#### Steps to Add a Self-Managed Certificate

   * Locate and select the **Certificates** section.
2. **Upload the Certificate**
   * Click on the **Upload Certificate** option.
3. **Input Certificate and Key**
   * **Enter SSL Certificate and Private Key**:
     * Ensure your SSL certificate file is in PEM format (typically a `.crt` or `.pem` file).
     * Ensure your private key file is in PEM format (usually a `.key` file).
   * **Copy and Paste Contents**:
     * Copy the contents of your SSL certificate and paste them into the **Certificate** field.
     * Copy the contents of your private key and paste them into the **Private Key** field.
4. **Save the Certificate**
   * Click the **Save** button to upload the certificate
5. **Review Certificate details**
   * **Common Name**: A name for easy identification.
   * **Issuer**: The organization that issued the certificate.
   * **Valid From**: The start date of the certificate's validity.
   * **Valid to**: The certificate's expiration date.
   * **Covered Domains**: Domains secured by the certificate.
   * **Thumbprint**: A unique identifier for quick reference.
6. **Activate the Certificate**
   * After saving, ensure the certificate is activated by clicking the **Activate** button (if applicable) in the Certificates section. This step is essential for enabling secure connections using the newly uploaded certificate.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.simptel.com/tf-platform/administration/organizations/projects/tenants/domains/certificates/configure-self-managed-certificates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
