# Create a Certificate
To create a Certificate, follow these steps:
1\. In the **DCD**, go to **Menu** > **Security** > **Certificate Manager**.
2\. Click **Create Certificate** from the **Certificate Manager** page under the **Certificates** tab.
3\. Choose the **Certificate type** to create:
* **Auto certificate:** This certificate type can be used for [CDN](https://docs.ionos.com/cloud/network-services/cdn).
* **Import a certificate:** This certificate type can be used for [Managed Application Load Balancer](https://docs.ionos.com/cloud/network-services/application-load-balancer) and [CDN](https://docs.ionos.com/cloud/network-services/cdn).
4\. Configure the following details based on the **Certificate type** to create:
{% tabs %}
{% tab title="Auto certificate" %}
{% hint style="info" %}
**Prerequisite:** Make sure that the domain for which you are requesting the certificate has its zone managed through the [Cloud DNS](https://docs.ionos.com/cloud/network-services/cloud-dns).
{% endhint %}
* In the **Certificate Provider**, **Select Provider** from the drop-down list. The list displays all the created ACME providers. To create a new one, see [Create ACME Provider](https://docs.ionos.com/cloud/security/certificate-manager/dcd-how-tos/create-acme-provider).
* In the **Properties**, configure the following:
* **Certificate Name:** Enter a name to identify the certificate uniquely.
* **Common Name:** Enter a common name for the certificate.
* **Key Algorithm:** From the drop-down list, choose the type of Rivest-Shamir-Adleman (RSA) algorithm for the certificate. RSA is a widely used public-key encryption algorithm for secure data transmission. It generates key pairs and digital signatures.
* *(Optional)* **Subject Alternative Names:** You can add up to 10 names to the certificate.
{% hint style="info" %}
**Note:** Alternatively, you can also create an auto certificate from **Certificate Manager** page > **ACME Providers** and click **Create Auto Certificate** next to an existing **ACME Provider**. For more information, see [Create a Auto Certificate from ACME Providers](#create-a-auto-certificate-from-acme-providers).
{% endhint %}
{% endtab %}
{% tab title="Import a certificate" %}
* In the **Properties**, configure the following:
* **Certificate Name:** Enter a name to identify the certificate uniquely.
* **Certificate:** You can drag or upload a file in the Privacy-Enhanced Mail (PEM) format or enter the content of the certificate file.
* **Certificate Chain:** Drag or upload a file in the PEM format or enter the content of the certificate file, including the certificate chain, a series of certificates that establish a chain of trust from the end-entity certificate to a trusted root certificate.
* **Private Key:** Drag or upload a file in the PEM format or enter the content of the certificate file that includes the private key information necessary for decryption and signing.
{% endtab %}
{% endtabs %}
5\. Click **Create** to apply to the certificate configuration.
{% hint style="success" %}
**Result:** Based on the **Certificate type** chosen, the corresponding Certificate is successfully created.
{% endhint %}
## Create a Auto Certificate from ACME Providers

3\. Click **Create Auto Certificate** against the **ACME Provider** for which you want the certificate to be created.
4\. Configure the **Certificate Provider** and **Properties**. For more information, see **Auto certificate** details under [Create a Certificate](https://docs.ionos.com/cloud/security/certificate-manager/dcd-how-tos/create-certificate).
5\. Click **Create** to apply to the certificate configuration.
{% hint style="success" %}
**Result:** The **Auto certificate** is successfully created for the selected **ACME Provider**.
