There are many reasons why you may be looking for open-source public key infrastructure (PKI) software. Maybe you need to enable authentication and encryption for IoT products you deliver to the market. Or maybe youre issuing certificates into a microservices environment to secure machine-to-machine connections. In any case, youve got options.

This blog will discuss the best open-source PKI software tools available today and provide tips on choosing the right tool for your needs.

First off, lets begin with a few definitions. PKI is used to issue certificates that enable authentication, encryption, and digital signatures for multiple use cases.

Authentication: proving your identity to a website or other entity

Encryption: protecting data from unauthorized access

Digital signatures: verifying the authenticity of a message or document

Open-source PKI solutions are a type of CA software that is available for anyone to use, modify and distribute. Open source software could be used for publicly trusted SSL/TLS certificates or, more commonly, as a private certificate authority (CA) for internal trust within an enterprise.

The code for these tools is typically published under an open-source license, allowing anyone to view, edit and redistribute the software.

Developers and engineers increasingly leverage PKI to embed security into their products or application development and delivery pipelines. Open source certificate authority (CA) software is a great way to get started with PKI.

There are many different open-source PKI software tools available today. Here weve broken down the four most common open source PKI solutions, including key considerations and recommendations when choosing the right fit for your use case.

EJBCA is a Java-based PKI solution that offers both enterprise and community editions. EJBCA Community Edition (CE) is free to download and has all the core features needed for certificate issuance and management. It includes multiple certificate enrollment methods, as well as a REST API. EJBCA was developed by PrimeKey, now a part of Keyfactor, and it is the most widely trusted and adopted solution for open-source PKI CA today.

Core capabilities include:

EJBCA Enterprise Edition (EE) includes features for production-ready environments, including high availability, clustering, authentication, advanced protocol and HSM support, professional support and services, and deployment flexibility. EJBCA Enterprise can be deployed as a turnkey hardware appliance, software appliance, cloud-based, or SaaS-delivered PKI.

Dogtag Certificate System (also known as Dogtag PKI) is an open-source certificate authority (CA) that supports many common PKI use cases. It offers a web-based management interface that allows you control over your certificates while also supporting multiple formats so that they can easily fit different use cases.

Core capabilities include:

The OpenXPKI is a toolkit based on OpenSSL and Perl that can create, manage, and deploy digital certificates. It includes support for multiple certificate formats and an online interface to help you oversee your PKI workloads.

Core capabilities include:

Step-ca is a simple yet flexible CLI-based open-source PKI tool that can create and manage digital certificates. It similarly includes support for multiple certificate formats and integrates with tools like Kubernetes, Nebula, and Envoy.

Core capabilities include:

When choosing an open source PKI management tool, there are several factors you will want to consider based on your specific use case and requirements.

Setting up and running a PKI isnt for the faint of heart. Even the best tools can create vulnerabilities if they are not properly configured and deployed. Open-source PKI solutions should be easy to deploy, with published containers offering the simplest method. They should also provide an easy-to-use interface for configuration, reporting, and management.

Once you have your PKI up and running, youll need to integrate certificate issuance and management workflows with your tools and applications. Industry-standard protocols such as ACME, SCEP, EST, and CMP provide certificate lifecycle management and enrollment capabilities. A REST API is also important to offer additional extensibility and functionality specific to the tool you choose.

Good documentation is essential for any PKI solution. Be sure to check that the documentation is up-to-date and easy to understand. Support typically isnt available with open-source projects, so youll need to ensure that you can set up and deploy the solution independently.

You should also ensure that theres a solid community to provide support and guidance when you need it. A good indicator of an active community is to check the number of downloads, discussions, and online forums where end users can discuss features and assist one another.

Security isnt static, and your PKI shouldnt be either. Ensure that your open source PKI solution is actively developed and maintained by the community and project owner. This ensures that vulnerabilities are addressed swiftly, and new features and functionality are continuously available as the PKI landscape evolves.

If something goes wrong with your PKI implementation, youll need access to troubleshooting documentation. Make sure the supplier you choose offers thorough documentation and a commercial/premium support agreement available from the vendor with an enterprise version, should the need arise to upgrade.

If you need enterprise-grade features, be sure to choose a tool that offers a simple path to upgrade. A full-featured enterprise PKI should be able to handle the increased load of large-scale production environments without compromising performance or security. To support these requirements, youll need capabilities like high availability, multi-node clustering, compliance certifications, advanced protocols, and hardware security module (HSM).integrations.

EJBCA CE is a powerful, flexible, and easy-to-use PKI solution used by everyone from developers and engineers to IAM and security teams to issue trusted identities for all of their devices and workloads. Here are just a few of the key reasons why teams choose EJBCA CE over open source PKI alternatives:

EJBCA provides a complete PKI solution that includes everything you need to get started. It supports CA, RA, and OCSP functionality out of the box and can easily scale to meet even the most demanding transaction workloads for certificate issuance and validation.

EJBCA is extremely flexible and can be easily extended to meet your specific needs. It supports pre-built plugins with other open-source tools such as HashiCorp Vault and Kubernetes, and it also supports SCEP, CMP, and REST API protocols. Advanced protocols such as ACME and EST are available with EJBCA Enterprise.

EJBCA is readily available for download from GitHub and Sourceforge. Its also available as a published container via Docker Hub, making it easy to deploy quickly and securely. It also offers a web-based GUI for centralized administration of CAs, audit logs, templates and policies, and more.

EJBCA is one of the longest-running CA software projects, with millions of downloads and time-proven robustness and reliability. Its built on open standards and a Common-Criteria certificate open-source platform.

EJBCA is supported by comprehensive documentation, including how-to guides, tutorial videos, troubleshooting guides, and use cases. This makes it incredibly easy for end-users to get up and running quickly and to get the most out of their PKI.

If you need an enterprise-grade PKI solution, EJBCA offers an easy path to upgrade from the community edition to the enterprise edition. EJBCA Enterprise is available in many different forms and flavors to meet your specific requirements for simplicity, availability, and compliance.
