Nexum · Verification

Verify an examination.

Every examination is digested, signed by its analyst, its reviewer and the house, and timestamped by an independent authority. Checking those three things needs nothing from Nexum but the examination’s own files and the public key log.

Verification confirms this is what Nexum delivered, unaltered, at this version. It does not confirm the company’s claims or endorse the company.

For technical readers

You need openssl 3.0 or later, jq, xxd, curl and git, and the examination’s four files, named by its reference and version: the canonical JSON, the signature block, the timestamp token and, where present, the OpenTimestamps proof. The founder downloads them from their copy of the examination; for an entry published under its name, anyone may. Each check prints ok or FAILED.
