InstDrop uses WebRTC technology, which automatically encrypts all data using DTLS and SRTP protocols. Here's how you can verify it yourself.
WebRTC (Web Real-Time Communication) is a modern web technology that enables peer-to-peer communication directly between two devices.
All data transmitted via WebRTC is automatically encrypted using:
This means that neither the server operator nor anyone on the network can read the contents of your files.
Proof of P2P transfer in Developer Tools (any browser):
You'll see only one WebSocket connection:
wss://instdrop-production.up.railway.app/ws Detailed view of encryption in Chrome or Edge:
Open in a new tab:
chrome://webrtc-internals Check these key details:
dtlsState: connected – confirms active DTLS encryptiondtlsCipher – shows the encryption algorithm (e.g., AES_128_GCM)srtpCipher – encryption for data (e.g., AES_CM_128_HMAC_SHA1_80)How to verify that your files don't go through the server:
Open the Network tab in Developer Tools (F12) and monitor traffic while sending files or texts. You won't see any data transfer – only WebSocket messages for signaling. Your files never pass through the server.
This verification only works during an active connection. After disconnection, encryption information is no longer available.
WebRTC encryption is integrated directly into the browser and works automatically. It cannot be disabled or bypassed.
For highest security, always use the latest browser version and connect via HTTPS.
