EviCypher Webmail & Cloud

EviCypher Webmail is an extension that only works with NFC devices that are compatible with Freemindtronic's EviCypher technology.

To use EviCypher Webmail, the user must have :
– The Chromium-based browser extension such as Edge.
– An NFC device with EviCypher Webmail technology,
– The Freemindtronic Android application installed on an NFC-enabled phone,

– EviDNS ZeroConf software installed on your computer

After pairing the NFC device to the phone, and then the phone to the web browser extension, an encrypted communication tunnel is then established from end to end between the digital devices of the EviCypher product family. After this final step, everything is automatic.

The EviDNS ZeroConf software is a software developed by Freemindtronic. It allows to quickly find terminals such as NFC phones, connected on the same local network. It collects the IP address and port number of the paired NFC phone to inform the EviCypher Webmail extension.

How does it work?

The extension automatically adds contactless encryption and decryption functions via the NFC device to web browser-based email services such as Outlook, Gmail, Yahoo mail, Andorra Telecom Correu, Proton mail, HCL Domino Webmail, Roundcube Webmail.

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.
