TechFlow News — Open-source blockchain protocol KILT Protocol has announced the launch of DIDsign, enabling users to sign and verify documents privately and securely in a decentralized manner. DIDsign aims to make online services in Web3 more convenient and secure.
DIDsign allows users to directly sign any digital file—including PDFs, audio, video, and software—using a unique DID within their browser. Users can download signed files (or a set of files) along with the signature in zip format to their device, and send them via email, Telegram, WhatsApp, or other platforms. Recipients can easily confirm that the files have not been tampered with. Moreover, signing, sending, and verifying files are completely free.
