SecureBlackbox 2026 brings full post-quantum support across the board: transport components now support ML-KEM key exchange, including hybrid variants based on NIST and Edwards curves, and ML-DSA signatures are integrated throughout the PKI and AdES stack.
Digital signature support also gains Trusted Lists v6 (the European standard), Delta CRLs for broader PKI coverage and faster chain validation, and the CSC v2 protocol for smoother third-party interoperability.
Transport components add OpenSSH certificate support for trust-based client and server authentication, plus HTTP Server-Sent Events (SSE) support for easier integration with real-time architectures.
