C.E.R.T.O. certifies web pages, files, email, chats and cloud content autonomously, without intermediaries and with full legal value.
Do-it-yourself forensic capture: you turn online content into a bundle that holds up in court — one even the opposing party can verify. Without calling in an expert.
C.E.R.T.O. acquires and seals nine kinds of digital content. Every acquisition produces a BagIt bundle signed with Ed25519, with a double RFC 3161 timestamp, a CASE/UCO description, a forensic report and 5-year archiving.
How the content is captured changes from module to module, but from there every exhibit follows the exact same documented path — fingerprint, signature, timestamp, description and verification — without a single bit being altered.
Forensic collection of the content and its origin metadata, using each module's specific method.
Computation of MD5, SHA-1, SHA-256 and SHA-512 hashes that uniquely identify each file.
BagIt 1.0 bundle signed with an Ed25519 key bound to the device identity.
Double RFC 3161 timestamp — inner anchor and outer seal — with a free cascade and optional eIDAS InfoCert.
CASE/UCO and offline verification by anyone; secure archiving for five years.
Anyone can dispute a screenshot: "you edited it", "that's not the real date". A C.E.R.T.O. bundle can't be. Together with the evidence you hand over a digital fingerprint (a code that changes if even a single bit is touched, so tampering becomes obvious) and a certified timestamp (the official, non-falsifiable date of the acquisition).
And the decisive point: the opposing party can run the verification itself, offline and without trusting you. The bundle is checked with open, standard tools (BagIt, CASE/UCO — the internationally recognized formats for digital exhibits). If the file is authentic, verification confirms it; if someone tampered with it, it shows. There's no arguing with data like that.
