How it works

The Qryptr device has cryptographic software, a keyboard, camera, screen and is based on the RP2040 microcontroller.

  1. Get your Qryptr device: Each person gets their own Qryptr device.
  2. Generate an unique ID: When you first use your Qryptr, you can generate a new ID for your device.
  3. Share your ID safely: You can share this ID with others by showing them a QR code on your Qryptr screen. It’s best to do this in person to avoid impersonation.
  4. Add a contact: Scan someone else’s QR code with your Qryprt to add them as a contact.
  5. Send encrypted messages: Write your message on your Qryptr. It will be encrypted such that only the other person’s Qryptr can decrypt it.
  6. Share messages through any app: Take a picture of the generated QR code with your phone and share it using any messaging app you like (Whatsapp, Signal, etc.).
  7. Read the message: The other person scans the QR code with their Qryptr device, which decrypts the message and shows them what you wrote.

 

Because everything stays inside the Qryptr device, no one can intercept your messages!

FAQ

What is qryptr?

Qryptr is a secure messaging device designed to secure your messages by offering advanced endpoint protection alongside end-to-end encryption offered by general messaging apps such as Whatsapp or Signal

End-to-end encryption is great, but will not protect you from spyware or being targeted by advanced persistent threats.

Qryptr is for anyone who values security and wants to ensure their communication stays confidential. This can include individuals, businesses, or anyone who handles sensitive information such as system administrators, public servants, lawyers or executives.

Technical Questions:

Reading, writing, encryption and decryption is done on a seperate, airgapped device. Messages are spread using regular smartphones or other networked infrastructure.

Qryptr uses authenticated encryption with Curve25519 keys, and ChaChaPoly cipher.

In most cases, you would use a smartphone to photograph and spread encrypted messages created by Qryptr. However, you can also use your laptop or a plain old printer. You can get creative.

Qryptr aims to use the simplest hardware and software possible such that it is fully auditable. All hardware and software are open-source so anyone can verify it’s security.
