DIDsign

DIDsign is a decentralized way to sign and verify files privately and securely, built on KILT. DIDsign is designed to make online services more convenient and safer in Web3, the next generation of the internet. DIDsign allows you to sign any digital file — PDFs, audio, video, software — directly in your browser using a unique decentralized identifier (DID). You can download your signed file (or group of files) together with the signature to your device as a zip file and send it to anyone via your preferred method (email, Telegram, WhatsApp, etc.). The recipient can then easily verify that the file has not been tampered with. Signing, sending and verifying files is always free! Using DIDsign, several people can sign the same document separately and confirm that it was signed. For example if a contract needs to be approved by several parties, each party can sign it and send their signature to the others. The document can then be checked against each signature, showing that each party signed the document in its original form.
