Brazil adds post-quantum algorithms to its national certificate system
3 FEBRUARY 2026, BRASILIA
Brazil added post-quantum algorithms to its national certificate system, ICP-Brasil, through Normative Instruction 35, dated 30 January 2026 and published on 3 February 2026. The instruction brings ML-DSA and ML-KEM into the system, and GOV.BR targeted its first advanced signatures using them in the first half of 2026. The change moves Brazil from discussing post-quantum cryptography to embedding it in national infrastructure.
The step carries legal force. Adding the algorithms to ICP-Brasil makes them part of a binding national standard rather than voluntary guidance. Because ICP-Brasil underpins digital signatures and certificates across Brazilian government and commerce, the change reaches a broad base of users who rely on the system for trusted digital identity.
Certificate systems are a natural place to add post-quantum support. ICP-Brasil anchors digital identity and signatures, so enabling it to issue quantum-resistant certificates protects the signatures and identities that depend on it. By making the algorithms available in the national system, Brazil gives its public and private sectors a sanctioned path to quantum-resistant certificates.
Why it matters. Brazil has made post-quantum algorithms part of a binding national certificate standard, one of the more concrete regulatory steps in the region. Because ICP-Brasil underpins trusted digital identity across the country, the change gives organizations a sanctioned route to quantum-resistant signatures. Entities that rely on ICP-Brasil certificates can plan to adopt the new algorithms as the system and GOV.BR roll them out.
