Chiffrement sans contact des messageries instantanées, du courrier électronique et des réseaux sociaux via la technologie EviCypher…
The extension only works with devices that are compatible with Freemindtronic's EviCypher technology.
To use the webmail encryption extension, you must have:
- The Chromium-based browser extension such as Chrome.
- An NFC device with EviCypher technology,
- The Freemindtronic Android application installed on an NFC-enabled phone,
- EviDNS ZeroConf software installed on your computer
After contactless pairing of the device to the phone, and then the NFC phone to the web browser extension, an encrypted communication tunnel is then established from the devices end to end. After this last step, everything is automated.
The EviDNS ZeroConf software is a software developed by Freemindtronic. It allows to quickly find terminals such as phones, connected on the same local network. It collects the IP address and port number of the paired phone to inform the EviCypher Webmail extension.
How does it work?
The extension automatically adds contactless encryption and decryption functions via the device to web browser-based email services such as Gmail, Outlook, Yahoo mail, Andorra Telecom Correu, Proton mail, HCL Domino Webmail, Roundcube.
End-to-end encryption from human to human!
Indeed, emails always remain encrypted on the computer, phone or mail server, even when displayed on a screen.
To access the emails in clear text the user must have an NFC device and the appropriate key for encryption and decryption. If necessary, he will also have to validate the trust criteria associated with the key. Thus only the human holding the device can encrypt and decrypt the emails.
Advantageously, even if the email service is corrupted, the email always remains encrypted, whether it is received, sent or awaiting final deletion.
Decryption is performed on demand, ephemerally, in the volatile memory of the computer or phone. Thus, the plaintext message is never saved, as it is automatically deleted after reading.
The extension is published as open source on Github by Freemindtronic under the GPL-3.0 license.
