About Our Encryption

End-to-end encryption consists of securing data between two users or end points using a private & public key for each user or end point. The data is encrypted on the end devices and remains encrypted everywhere its sent and stored until the authorised recipient opens the message and decrypts it on his or her device. Neither Vox Messenger nor any of the networks, servers, databases, or third party services will see anything but scrambled data passing through.

 

  • We cannot and do not read your messages (unlike WhatsApp)
  • We do not use ads or retargetting (unlike Facebook Messenger)
  • We do not sell your user data (unlike Facebook)
  • We use an open source crypto library (unlike Telegram)
  • We support access from multiple phones (unlike Signal)

 

The underlying encryption is provided by Virgil Security, a platform to bring powerful cryptography to every application. Built by a world-class team of cryptographers, our encryption is powered by a state-of-the-art open source crypto library, complete with elliptic-curve keys 200x harder to break than RSA. e3Kit is a client-side SDK that simplifies work with Virgil services and presents the easiest way to add full end-to-end encryption (E2EE) security to your digital solutions. e3Kit interacts with Cards Service, Keyknox Service and Pythia Service and supports multi-device access and group chat features.

Links to individual algorithms and more details on the underlying open source crypto library can be found under “SDKs and Tools” -  https://developer.virgilsecurity.com/docs/sdk-and-tools

Encrypted

End-2-End Encryption utilising Virgil e3Kit. High speed bullet-proof encryption. If your data is only encrypted in transit and at rest, it’s still vulnerable to developer error and security issues at your service providers. With end-to-end encryption, only your end-users decrypt their data – protecting them and you.

Instant Messenging

Secure and encrypted instant messaging including emojis. Can you tell if a message really came from a trusted user or from somebody else? Our system uses multiple layers of user key verification in order to ensure the integrity and utility of messages.

Voice Calls

High quality voice calls on demand whenever and wherever you need them most. Speak to anyone in the world with an internet connection or a phone number. Clear & crisp voice quality.

Video Calls

High quality, crystal clear, on demand video calls to friends and families. Make and receive, crisp and crystal-clear 1080p, real-time video calls to anywhere in the world over a data connection or WiFi.

Media Sharing

Share what is important to you, everything from photos and videos to documents and your location.

Security

Never leave a trace again. Encrypted and fully audited, featuring 'Incinr8', true handset and database burning of your messages. Decrypt and verify that the data wasn’t tampered with or 'peeked' at.
