Overview - How to Create a Private Certificate in Azure Key Vault
Azure Key Vault is the best way to manage certificates in Azure, it allows you to securely distribute your certificates to all your Azure resources. While Azure Key Vault (AKV) has automatic rotation for public certificates it does not work for your private certificate authority. To help you automatically rotate your private certificates (even for your Windows ADCS CA with our ADCS connection) in Key Vault, we have created a seamless integration with Azure Key Vault to enable users to create, request, and manage certificates in a few clicks from a single place.
How to Create a Certificate in AKV with EZCA
- Navigate to https://portal.ezca.io/
- Navigate to Domains.
- Click the “Request Certificate” button on the domain you want to request a certificate for.
- This will pre-populate the Subject Name and Subject Alternate Names with the selected domain.
- If this certificate requires more subject alternate names (Usually for other domains that might use this certificate), add them in the DNS Names section.
- By Default, EZCA will request the certificate to be the maximum validity allowed by your administrators. If you want to decrease the lifetime of the certificate, adjust the validity slider.
- Change the Certificate Location to Azure Key Vault
- Select the Azure subscription containing the Key Vault
- Select the Azure Key Vault where you want to store the certificate.
- For an automated lifecycle, select the “Auto renew certificate” option. This will enable EZCA automatically renew your certificate when it is over the defined rotation lifetime.
Enabling automatic renewal of certificates, automates the lifecycle of your certificates reducing the chances of having an expired certificate related outage.
- Adjust the slider to select at what percentage of the certificate lifetime do you want EZCA to automatically renew the certificate.
- Click the “Request Certificate” button at the top right of the form.
- Your Certificate has been created successfully
