chirpfile information
What is chirpfile?
chirpfile moves encrypted files between browsers without accounts, QR codes, or a shared Wi-Fi network. The sender's browser encrypts the file locally, uploads the ciphertext to a short-lived relay, and plays the decryption key as a short audio chirp. Any nearby device with chirpfile open in a browser tab decodes the chirp with its microphone, fetches the ciphertext, and decrypts it locally.
Because the key travels over sound instead of the network, chirpfile works across every kind of network boundary -different Wi-Fi networks, corporate firewalls with client isolation, hotel Wi-Fi, VPNs, cellular-to-Wi-Fi, air-gapped viewers. It's the same acoustic data-over-audio principle that the open-source ggwave library uses, applied to the practical problem of moving a file from your phone to a laptop when AirDrop, LocalSend, Snapdrop, and PairDrop all refuse to see each other.
Highlights: • AES-128-GCM encryption in the browser: the server sees ciphertext only • Zero-knowledge relay: keys never touch the network • Ephemeral by default: files expire minutes after transfer • Cross-platform: any modern browser on iOS, Android, macOS, Windows, Linux • No install, no account, nothing to configure • Built-in transparency panel showing exactly what leaves the device
