Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves these records existed by then and have not been changed since, by anyone, Rewindex included.

How the archive is checked, and what it cannot prove.

Rewindex captured a newer version after the last checkpoint; the next run () commits it.

Impact, status and times are the vendor’s own, as last archived. View on www.githubstatus.com (opens in new tab).
