Every document signed with SignBolt carries an Audit ID and the link signbolt.au/verify/<id> printed on the page. Enter that Audit ID below to confirm the signer, timestamp, and document integrity. SignBolt's audit records are Ed25519-signed, so you can also verify them offline without trusting our servers.
Paste the printed ID or full verify URL from the signed PDF.
The existing verification record shows privacy-safe signing details.
Use the published Ed25519 key to verify the audit record independently.
SignBolt records 6 audit fields for each signing event, then signs the audit record so recipients can verify where it came from.
| Field | What it proves |
|---|---|
| Audit ID | Unique reference for this signing event |
| SHA-256 of the original file | The exact document that was presented for signing |
| ISO-8601 timestamp | When it was signed |
| Signer identity | Verified email / name on the session |
| IP + user agent | Where the signature originated (private - not shown publicly) |
| Ed25519 signature | Cryptographic proof the audit record came from SignBolt |
Each audit record is Ed25519-signed by SignBolt. A third party can fetch the public verification key, check the audit signature, and confirm the record was produced by SignBolt without relying on a live trust decision from our servers.
