True E2EE Pair Programming via ECDH.

When you use cloud-based pair programming tools, your source code is transmitted in plain text to the host company's routing servers. Even if the WebSocket connection is secured via TLS/SSL, the server itself can read, store, and analyze your proprietary algorithms. For enterprise compliance, this is a fatal flaw.

NitroIDE guarantees absolute zero-knowledge collaboration. Before a single keystroke is transmitted over our WebRTC mesh, the peers negotiate a secure, shared cryptographic key using Elliptic Curve Diffie-Hellman (ECDH) via the browser's native Web Cryptography API.

The ECDH Key Exchange

ECDH is a mathematical miracle that allows two browsers to agree on a shared secret key over an insecure channel, without ever transmitting the key itself. When Alice invites Bob to a NitroIDE workspace, both browsers generate a public/private keypair using the P-256 elliptic curve.

// Generating an ephemeral Elliptic Curve keypair
const keyPair = await crypto.subtle.generateKey(
  { name: 'ECDH', namedCurve: 'P-256' },
  true, ['deriveKey']
);

// Deriving the shared AES-GCM secret using the peer's public key
const sharedSecret = await crypto.subtle.deriveKey(
  { name: 'ECDH', public: peerPublicKey },
  keyPair.privateKey,
  { name: 'AES-GCM', length: 256 },
  false, ['encrypt', 'decrypt']
);

Perfect Forward Secrecy: NitroIDE generates fresh, ephemeral ECDH keypairs for every single collaborative session. Once you close the browser tab, the keys are wiped from RAM forever. Even if a bad actor recorded all the encrypted network traffic, they could never decrypt it later.

Hardware-Accelerated AES-GCM

Once the shared secret is established, every cursor movement, file save, and terminal command is encrypted using AES-GCM before hitting the network. Because the Web Crypto API is backed by native OS libraries (like OpenSSL or BoringSSL), this encryption happens at the hardware level, resulting in zero noticeable latency during real-time typing.
