Welcome to the documentation of the Digital Evidence Preservation Toolkit, a one-click tool to archive and annotate webpages while demonstrating chain of custody throughout.


The DEPToolkit is a proof-of-concept software for researchers and small teams sifting through online material.

With only one click of the mouse, the material will be archived in a framework demonstrating chain of custody and stored durably. Once included in the growing database, users will be able to go back to search through and annotate the material, and to export working copies of said material for publication and dissemination.

A database built thusly can be handed to a prosecutor ten years down the line, and they will be able to say with mathematical certainty: β€œthe material in this archive is identical and contemporary to the one saved at the time, ten years ago.”
