Overview

As mentioned in the CA Overview a Root CA is needed to be the root of trust for your PKI Deployment. In this page we will guide you on how you can create your own Root CA either using EZCA or creating your own offline CA.

Getting Started

1. Go to https://portal.ezca.io/
2. Login with an account that is registered as a PKI Admin in EZCA.
3. Navigate to Certificate Authorities.
4. Click on the “Create CA”
5. Select Root CA.
6. Click Next

Entering CA Information

1. Enter Common Name: This is the name of the CA how it will appear in the certificate.
2. (Optional) Enter CA Friendly Name This is the name that will appear in the EZCA portal, by default we will use the Common Name
3. (Optional) Enter the Organization The Organization field is an optional certificate field that usually has the company name.
4. (Optional) Enter the Organization Unit The Organization Unit field is an optional certificate field that usually contains the unit that runs this CA (For example: IT or HR).
5. (Optional) Enter the Country Code The Country Code field is an optional certificate field that identifies the country where this CA is located.
6. Click Next.

Cryptographic Requirements

1. Unless you have specific compliance or security requirements, leave the default cryptographic values for best security and compatibility.

Validity Period

1. Select your Validity Period Learn more about Validity Period best practices
2. Enter a Notification Email this email address (as well as the PKI Administrators) will get all the notifications for the lifecycle of the CA.
3. Select the lifecycle action you want EZCA to take when expiry of the CA is approaching

   For Root CAs we recommend to have a manual Lifecycle since the new Root will have to be added to the trusted root stores of your clients which requires manual steps from the IT team.

4. Select the percentage of lifetime of the certificate when you want EZCA to start taking Lifecycle actions.

CA Certificate Revocation List

1. Select if you want this CA should issue a CRL (Highly recommended)
2. Click Next.

CA Certificate Revocation List Advance Settings

2. Enter the desired CRL Validity Period in days
3. Enter the desired CRL Overlap Period in hours
4. (Optional) Enter the CRL endpoint where you will publish your CRLs

   Custom CRL endpoints are supported by EZCA by adding the CRL endpoint as the CRL endpoint in the certificate. However, your PKI admins are responsible from getting the CRL from EZCA and posting it in that specific endpoint.
