User identity and end-to-end encryption on webAI are split across two focused facades:
FacadePurpose
sdk.identityRead the user’s device identity (), display name, profile image, and authentication state. Update display name and generate short ODID forms.
sdk.cryptoEncrypt and decrypt data with end-to-end encryption using peer public keys.
Apps access them through the platform bridge object: 
const sdk = window.apogeeSDK || null;
if (!sdk) return;
const identity = sdk.identity.getState();
Declare identity and crypto in your shell manifest under requires.managers as needed.

​
Full reference

The complete reference for each facade lives in the in-app Developer panel.

​
Open the Developer panel

  1. Open Settings → Experimental and toggle Developer Mode on.
  2. A terminal icon appears in the top right of the app. Click it to open the Developer panel.
  3. Go to the Documentation section → Docs tab → identity or crypto.

​
End-to-end encryption

The sdk.crypto facade provides encryption primitives for securely exchanging data with other peers. You pass the recipient’s public key (as a JSON Web Key) when encrypting, and your own private key when decrypting received data. See the Developer panel for the current method signatures, parameter shapes, and interactive examples.
