Design principles

The constraints that keep independent verification possible.

These are system constraints, not product features. CERTCRYPT is defined by the conditions required for independent verification to remain possible over time, and by what the system deliberately refuses to do.

Core principles

Each principle protects a condition required for independent verification to remain possible without data custody, institutional dependence, or system-level tracking.

  1. Zero-data by design

    The protocol surface does not hold documents, identities, or operational records.

    Verification depends on the certificate, the original material, and the public rules, not on platform-held data.

  2. Proof without data custody

    Verification does not require data custody or access to internal systems.

    It relies on the certificate, the original material the verifier obtains from whoever holds it, and the public rules, not on platform-held data.

  3. Unlinkability

    Attribution per certificate stays strong; cross-certificate correlation does not.

    Certificates expose no stable references that would enable cross-certificate correlation or reconstructable subject activity; the protocol does not turn certificates into tracking artifacts.

  4. Deterministic verification

    Verification produces the same result regardless of who performs it.

    Given the same inputs and rules, outcomes converge.

  5. Institutional independence

    Verification does not depend on the issuer or CERTCRYPT remaining available as a live service.

    Once an artifact is Independent, later evaluation can be reproduced under public rules without a party remaining online as the verification authority.

  6. Infrastructure neutrality

    The protocol is independent of specific platforms, providers, or infrastructures.

    Verification rules remain stable across environments.

  7. Interpretation boundaries

    CERTCRYPT does not interpret legal meaning or semantic truth.

    Its role is to preserve verifiability under public rules.

Constraints define the system

These principles are not optional features.

They define the conditions under which verification remains possible over time.

To see how these principles translate into operation, read how certificates are produced under the public rules.
