async function encryptMessage(plaintext: string, conversationKey: CryptoKey): Promise<string> {
const encoder = new TextEncoder();
const iv = crypto.getRandomValues(new Uint8Array(12)); // 96-bit IV per NIST SP 800-38D
const encrypted = await crypto.subtle.encrypt(
{ name: "AES-GCM", iv, tagLength: 128 },
conversationKey,
encoder.encode(plaintext)
);
// Format: base64(iv + ciphertext + authTag)
const combined = new Uint8Array(iv.length + new Uint8Array(encrypted).length);

false,
["encrypt", "decrypt"]
);

const { ciphertext: kemCiphertext, sharedSecret } = mlKem768.encapsulate(recipientPQKey);
const aesKey = await hkdfSha256(sharedSecret, 32); // Derive 256-bit AES key

}4. Signal Protocol — Perfect Forward Secrecy
X3DH key agreement and Double Ratchet algorithm for per-message forward secrecy in Smart Chat.

decryption: 'Client-side after reception';
