ECDSA

App.tsx

import { type EcdsaSession } from '@silencelaboratories/silent-shard-sdk';

export const exportKey = async (session: EcdsaSession) => {
  // Creating a new keyshare for demo purpose. In real application, you can use an existing keyshare.
  const keyshare = await session.keygen();
  console.log('Keyshare: ', keyshare.keyIdHex);

  const privateKeyHex = await session.export({
    keyshare,
  });
  console.log('Exported private key: ', privateKeyHex);
};

EdDSA

App.tsx

import { type EddsaSession } from '@silencelaboratories/silent-shard-sdk';

export const exportKey = async (session: EddsaSession) => {
  // Creating a new keyshare. In real application, you can use an existing keyshare.
  const keyshare = await session.keygen();
  console.log('Keyshare: ', keyshare.keyIdHex);

  const privateKeyHex = await session.export({
    keyshare,
  });
  console.log('Exported private key: ', privateKeyHex);
};
