DIDsign

DIDsign is a free, decentralized way of signing and verifying digital files. It is built on KILT and allows users to sign any digital file, such as PDFs, audio, video, and software, directly in their browser using a unique decentralized identifier (DID). Users can download the signed file (or group of files) and the signature as a zip file to their device and send it to anyone via their preferred method (email, Telegram, WhatsApp, etc.). The recipient can then easily verify that the file has not been tampered with.
