Witness Vault is a free, open-source tool that packages a confidential file or text note into a single encrypted HTML file that any recipient can open and decrypt in a plain web browser, with no software install, server or cloud dependency on either side, and a strict policy that blocks all outbound network requests. It is aimed at people who need to share something confidential securely without asking the recipient to install anything.
