Key material helpers

Two small helpers that produce a raw session-key pair with no manager, no state, and no persistence. Reach for these when you only need a keypair — nothing to load, persist, sign with, or subscribe to.

Both return the same SessionKeyMaterial shape:

createSessionKey

Generate a fresh keypair.

import { createSessionKey } from "@symmio/session-key";
 
const key = createSessionKey();
console.log(key.address); // 0x…

sessionKeyFromPrivateKey

Restore the material from an existing private key — useful when importing a key that lives outside the manager.

import { sessionKeyFromPrivateKey } from "@symmio/session-key";
 
const key = sessionKeyFromPrivateKey(privateKey);
console.log(key.address);

When to use the manager instead

These helpers give you a keypair and nothing more. When you need persistence, expiry, rotation, signing, or state subscription, use createSessionKeyManager — or importPrivateKey to bring an existing key under manager control.
