Certificate management using CZERTAINLY and Certbot

As the world is progressing through the digital era, it is more needed now than ever to protect the integrity and security of information over the internet. A single breach in the infrastructure can cause millions to rectify. And many outages of the services are cause by expired or invalid certificate.

Many tools and solutions exists but the general question we all have is “How do we choose the correct one for our infrastructure?”. We introduce you to CZERTAINLY!

CZERTAINLY is an open-source platform for effective and efficient certificate lifecycle management for companies of any size and individuals. One of its goals is to provide an easy and affordable way to secure digital communication and support information security in more and more connected world.

Web applications

Whenever we host a web application to be accessed by users, we rely on various web server technologies and hybrid environments. (we can name a few like Apache, Nginx, Wildfly, Kubernetes, Nomad, VM, HAProxy, but the list is much more longer)

Once the application is hosted and is made available for others to use, the necessity of its security becomes on of the primary tasks. We issue SSL/TLS certificates to make them secure across the internet. But how do we make sure that we do not face breaches and outages because of the certificates?

For these purposes, we have protocols in place which are implemented by the servers and clients to make this process easy. One such protocol is ACME, which describes the process of automated certificate enrollment and management.

When it comes to securing the applications deployed on the web server, Certbot is the tool we usually turn around for help to automate the certificate management process.

CZERTAINLY is integrated with Certbot for this very purpose to make the whole process completely seamless and transparent, connecting to any certification authority!

Certbot - what is it?

Certbot is an easy-to-use, open-source ACME client that can request, revoke and renew certificates deployed on manually administrated web sites.

Made by Electronic Frontier Foundation (EFF), it remains the most common ACME client when it comes to manage certificates. It is a fully-featured extensible client for any ACME compliant servers which can automate the tasks of obtaining the certificates, configuring them on the web servers. Therefore, it works very well with the CZERTAINLY platform.

Certbot will ensure that the certificate deployed on the web server always stays up to date, thereby reducing the risk of outages and security breaches related to expired or invalid certificate.

To learn more about Certbot, refer to the official Certbot documentation.

CZERTAINLY and Certbot

CZERTAINLY platform implements the ACME protocol according to the RFC8555 – Automatic Certificate Management Environment (ACME).

Using CZERTAINLY as the ACME server, Certbot can use it for certificate management. The ability of the platform also enables the security team to control the attributes in certificates whenever needed using the concept known as RA Profiles.

We believe in simplicity and it is the key to effectiveness. You can enable an ACME server following the 3 simple steps:

  • Create ACME Profile
  • Enable ACME for RA Profile
  • Get the directory URL and start certificate management using Certbot

Interested and want to know more on how CZERTAINLY implements ACME? Read the Certbot integration guide and the documentation of ACME Implementation and managing ACME Profiles and Accounts.

Why CZERTAINLY?

The advantages of using CZERTAINLY as ACME server are obvious:

  • Simple configuration and easy to use
  • Ability to update attributes to issue certificate which are specific to certification authority
  • Ability to update the ACME server configuration with ease when needed
  • Integration with any technology through connectors, including proprietary
  • Overall control over the ACME Accounts

And all of that is open source and available for anyone!

Open-source implementation and support

CZERTAINLY platform and ACME support is part of open-source repositories. Start using the platform without any restrictions on number of certificates or number of services.

If you would like to receive support or professional services, our team is readily available to assist you, whether you want to deploy the platform, or create a new connector. Do not hesitate and give it a try!
