OpenXPKI
By White Rabbit Security GmbH
The typical implementation process for OpenXPKI software involves the following steps:
Initial Planning and Requirements Gathering: Define the organization's PKI needs, including certificate policies, workflows, and integration requirements.
Installation: Install OpenXPKI on a supported platform (e.g., Debian, Ubuntu, or RHEL) using provided packages or Docker images. A sample configuration is available for quick setup.
Configuration: Customize the YAML-based configuration files to define PKI Realms, workflows, authentication methods, and integration with external systems like HSMs or LDAP directories.
Database Setup: Create and configure the database (e.g., MySQL or PostgreSQL) to store certificates and workflow data.
Integration: Connect OpenXPKI with external tools such as ITSM systems, external CAs (e.g., DigiCert), or authentication systems (e.g., SAML, OAuth).
Testing and Validation: Test the system by simulating certificate requests, renewals, and revocations to ensure workflows function as expected.
User Training and Documentation: Train administrators and operators on using the web interface, command-line tools, and workflows for daily operations.
OpenXPKI can be highly customized to fit specific business needs, leveraging its flexible architecture and modular design:
Workflow Engine: OpenXPKI enables organizations to define and modify workflows for certificate lifecycle operations, such as issuance, renewal, and revocation. Custom workflows can be modeled using YAML configuration files and extended with Perl scripting for non-standard requirements.
PKI Realms: The software supports multiple PKI Realms within a single installation, allowing businesses to operate distinct namespaces and logical Certificate Authorities (CAs) with independent profiles, workflows, and policies.
Connectors: OpenXPKI includes a Connector framework that allows integration with external data sources like LDAP directories, SQL databases, flat files, and web services. This enables dynamic access to external authentication and authorization resources.
Customizable Enrollment Interfaces: Organizations can define an arbitrary number of enrollment interfaces (e.g., SCEP, EST, ACME), each tailored to specific client groups or operational scenarios.
Template-Based Certificate Generation: OpenXPKI allows the creation of certificates based on templates, enforcing naming conventions with regular expressions while simplifying user input requirements.
YAML-Based Configuration: All system configurations are managed through YAML files, which support overlays for environment-specific differences. This approach ensures auditability and easy version control using tools like Git.
Integration with External CAs: Businesses can delegate certificate issuance to external CAs like DigiCert, Sectigo, or SwissSign while maintaining centralized management within OpenXPKI.
Localization (I18N): The platform supports internationalization with Unicode characters in certificates and localized interfaces for global operations.
Custom Reporting: Reporting functions can be tailored to collect statistical data and generate Key Performance Indicators (KPIs) specific to the organization’s PKI Realms.
OpenXPKI training and support resources to assist new users in effectively utilizing their Public Key Infrastructure (PKI) software:
Documentation
User Manual: A comprehensive guide detailing the installation and use of OpenXPKI, targeting CA administrators and operators. It assumes familiarity with Unix shell operations and foundational PKI concepts.
Quickstart Guide: Provides step-by-step instructions for deploying and configuring OpenXPKI, including a public demo for initial familiarization.
Community Support
Mailing List: An active platform for general discussions, troubleshooting, and advice on managing OpenXPKI instances. Users can subscribe to engage with the community and receive updates.
Professional Support
OpenXPKI implements several security measures to protect data within its Public Key Infrastructure (PKI) system:
1. Cryptographic Key Protection
Hardware Security Module (HSM) Integration: OpenXPKI supports the use of professional HSMs, such as nCipher nShield and Safenet Luna CA modules, to securely store and manage private keys, enhancing the security of cryptographic operations.
Threshold Secret Sharing: In environments without HSMs, OpenXPKI can employ threshold secret sharing algorithms to protect private keys, ensuring that key material is divided into parts and requires a threshold number of parts to reconstruct, thereby preventing unauthorized access.
2. Database Security
Professional Database Support: The system supports various database backends, including commercial options like Oracle, commonly used in enterprise scenarios. This flexibility allows organizations to choose database systems that meet their security and compliance requirements.
3. Process Isolation
Separation of Process Logic: OpenXPKI's architecture emphasizes the separation of process logic from implementation details, reducing the risk of security vulnerabilities by isolating different components of the system.
4. Access Control
Authentication Mechanisms: The platform allows the configuration of various authentication methods, including integration with external systems like LDAP servers, to ensure that only authorized users can access specific functionalities.
Access Control Lists (ACLs): Administrators can define roles and permissions using ACLs, providing granular control over user access to system resources.
5. Logging and Auditing
Comprehensive Logging: OpenXPKI includes robust logging and auditing features, crucial for security-sensitive software, to monitor system activities and detect potential security incidents.
6. Workflow Customization
