zipper will be available as a standalone application on desktops (Mac, Windows, Linux), on mobiles (iOS, Android), as well as in any web browser. This will allow you to communicate and exchange documents conveniently whether you’re in the office, at home or on the road. Our prototype is a web application which you can test at: https://proto.zipper.im
zipper is the first instant messaging system to offer certified documents (or recommended letters) for the digital age. We are leveraging the blockchain technology for storing cryptographic reception receipts. Our prototype uses the Ethereum blockchain. Proof-of-reception is ensured by signing the certified documents electronically using a YubiKey, a secure hardware key implementing the U2F protocol also used by Google, Facebook, Microsoft and others for two-factor authentication.
CLOUD STORAGE INTEGRATION
Link your zipper account with your preferred cloud storage provider, so that all documents received through zipper get automatically uploaded to your storage account. A simple solution for backing up and conveniently accessing documents. We plan to support major storage providers such as Dropbox, Google Drive, and Microsoft OneDrive, as well as Swiss providers. We also offer an in-house cloud storage service at: https://cloud.zipper.im
SECURITY AND ENCRYPTION
zipper uses end-to-end encryption (implemented as a double ratchet algorithm based on the Signal protocol) for all messaging traffic, document transfer, and voice/video calling. Encryption keys can be easily backed-up in the application if needed. The zipper servers for front- and back-end are hosted in Switzerland only.
zipper Instant Messaging is a Swiss startup aiming to revolutionize business communication.
Our goal is to offer a state-of-the-art alternative to paper and email, in the form of an instant messaging system focused on security and convenience. Complex technologies such as authentication, encryption, and digital signature, are proposed in their easiest and friendliest forms to zipper users.
Do not hesitate to test our prototype. Simply create a new account (with just user ID and password) and start chatting with zipper Support or with a colleague already signed up.
