Decode JWT and OIDC artifacts locally, inspect time windows, audiences, algorithms, key hints, and claim exposure without uploading tokens. Claimcipher is an offline token inspection desk for developers and security practitioners who need to reason about JWT structure while keeping sensitive claims on device. Turn local JWT, JWK, and OIDC JSON evidence into a prioritized, editable review with explicit assumptions, ownership, and exportable decisions. KEY FEATURES - Native JWT, JWK, and OIDC JSON import and normalization - Interactive claim cipher - Editable tokens & keys with owners and evidence - Deterministic token findings scoring - Current-versus-proposed state comparison - Decision log with accountable disposition - Portable jwt evidence packet export - Private offline workspace with no account - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription Claimcipher decodes and checks recorded structure; it does not trust a token, fetch keys, validate a live issuer, protect an exposed credential, or replace server-side verification. Never paste production bearer tokens unless your handling policy permits it.
