BACnet International’s Cybersecurity Acceleration Program was developed to help suppliers jumpstart BACnet/SC by providing the means to efficiently generate, exchange, and manage these files, significantly simplifying system integration. The program developed BACCARI (BACnet Certificate Authority Reference Implementation Tool) to build and process files using the CARI file format, as proposed in 135-2020 Addendum cs. The tool’s zip file format conveys BACnet/SC CSRs to a certificate authority and returns the signed operating certificates. This tool is the industry’s standard for certificate authority implementation.
The BACCARI Certificate Authority software tool beta 3 was released in 2025 and the operating code has been made public (at no charge) in Q1 2026 to promote interoperable certificate signing and exchange. For more information, email info@bacnetinternational.org.
