Claimcipher: JWT Inspector

An offline token inspector: turn local JWT, JWK, and OIDC evidence into a prioritized, editable review — reason about claims while they stay on your device.

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.

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.
