IRONDOTS 與 Waver: Data Over Sound 使用情況與統計
IRONDOTS allows you to encrypt & decrypt messages into / from a QR code.
THE IRONDOTS PRINCIPLE
IRONDOTS protects your messages from access by hackers, companies and governments through physical separation and end-to-end encryption. The app can be used completely anonymously (without registration; without providing a phone number or email address). IRONDOTS is based on the "box" model of the open source NaCl Networking and Cryptography Library to transmit messages with a maximum length of 160 characters encrypted into a QR code.
COMMUNICATE WITHOUT TRACES
IRONDOTS is designed for offline operation, without an internet connection. We have simply not implemented the possibility to communicate with the Internet or other devices. Your secret certificate is stored encrypted with your password on the mobile phone/tablet. All this prevents the collection and misuse of personal information. IRONDOTS is fully compliant with the European Data Protection Act (DPA).
BEST ENCRYPTION
All messages are always end-to-end encrypted. You can be sure that no one except the intended recipient can read your messages. The key pair is generated and stored encrypted directly on your device. 256-bit long asymmetric keys are used, which are generated using elliptic curve cryptography (Curve25519). This asymmetric key is used to obtain a unique 256-bit symmetric key for each message sent.
NO ADS, NO TRACKERS, NO COOKIES
IRONDOTS is not financed by advertising and does not collect user data.

Waver allows you to send and receive text messages from nearby devices through sound waves.
This application can be useful for communicating with multiple nearby devices at once. Both audible and ultrasound communication protocols are available. The app does not connect to the internet and all information is transmitted only through sound. In order to receive incoming messages you only need to allow access to your device's microphone so that it can record nearby sounds.
How to use:
- Before starting - make sure the speaker of your device is enabled and disconnect/unplug any headphones. The app uses your device's speaker to emit sounds when sending a text message
- To send a message - tap on "Messages", enter some text at the bottom of the screen and click "Send"
- Any nearby device that is also running this application can capture the emitted sound and display the received message
- In the settings menu, you can adjust the volume and the transmission protocol that will be used when sending messages. Make sure to adjust the volume level high enough, so the sounds can be picked up by other devices
- Tap on "Spectrum" to see a real-time frequency spectrum of the currently captured audio by your device's microphone
File sharing in a local network:
As of v1.3.0 Waver supports file sharing. It works like this:
- Add files that you would like to transmit by sharing them with Waver
- In the "Files" menu, click on "Broadcast". This plays an audio message that contains a file broadcast offer
- Nearby devices in the same local network can receive this offer and initiate a TCP/IP connection to your device
- The files are transmitted over TCP/IP. The sound message is used only to initiate the network connections between the devices
- Waver allows sharing multiple files to multiple devices at once
