ContentLedger verification

Verify ledger record

This page recalculates the stored origin-evidence manifest digest, checks its canonical serialization, and independently reviews its archive, version-chain, timestamp-proof, and digital-signature references.

Verification results

Manifest digest

Valid

The SHA-256 digest was recalculated from the downloaded manifest bytes.

Canonical JSON

Valid

The manifest matches the deterministic ContentLedger RFC 8785 serialization profile.

Archive snapshot

Verified

The associated Wayback URL passed the plugin’s HTTP availability check.

Version chain

Valid

Any previous-manifest digest resolves to an earlier sealed record in this ledger.

Current content

Changed since recording

The current page is a different content version. This does not invalidate the sealed historical manifest.

OpenTimestamps proofs

Not timestamped

No OpenTimestamps calendar proof has been attached to this manifest digest.

Site digital signature

Ed25519 compact JWS

Cryptographic signature valid

The protected public key verifies the JWS and its claims bind this exact manifest digest and ledger entry.

The JWS issuedAt value is a signed claim, not an independent timestamp. The verified did:webvh log establishes append order and recorded authorization intervals, but does not by itself provide trusted external time.

Cryptographic validity, historical did:webvh authorization, authorization at a claimed signing time, and current assertion authorization are separate results. None independently establishes legal ownership, human identity, original authorship, first publication, or a trusted signing time.

Independent digest check

Download the canonical manifest without modifying it and calculate its SHA-256 digest with a local tool. The result must equal the manifest digest printed above.

sha256sum wp-contentledger-a4791543-9f05-4b63-9a62-39c0e15ce106.json

The signature is an RFC 7515 compact JWS using the fully specified RFC 9864 Ed25519 algorithm and an RFC 8037 public JWK. An independent verifier should validate the JWS, confirm its manifestDigest claim equals the SHA-256 above, and resolve the kid against this website identity's did:webvh JSONL log.
