B-Trust

B-Trust is a Bulgarian software publisher that specializes in digital identity and secure electronic transaction solutions, with its flagship product BISS serving as the official Borica-branded utility for creating qualified electronic signatures, managing smart cards and USB tokens, and granting citizens seamless access to national e-government portals and other trusted-service platforms. The application is engineered to meet the country’s specific legal and technical standards for qualified signatures, making it indispensable for accountants, lawyers, notaries, corporate executives, and individual taxpayers who regularly submit declarations, annual reports, or procurement documents to state agencies. By embedding support for local CA hierarchies, OCSP validation, and hardware security modules, BISS streamlines the otherwise fragmented steps of certificate enrollment, PIN verification, document hashing, and signature timestamping into one coherent workflow, while also offering batch-signing options for high-volume paperwork. Beyond public-sector compliance, the tool is frequently deployed inside private companies that exchange signed invoices, contracts, or customs forms through secure web portals, eliminating the need for handwritten approvals and reducing courier costs. Users launching BISS encounter a minimalistic dashboard that lists available certificates, highlights expiry dates, and provides one-click navigation to the most common e-services, thereby lowering the technical barrier for non-specialists. B-Trust software is available free of charge on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always install the latest version, and permit batch installation alongside other applications.
