Export Key

Please refer to the Session creation section to learn how to create a new session.

Full Example

ECDSA

App.tsx

import { 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.keyIdBase64);

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

EdDSA

App.tsx

import { 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.keyIdBase64);

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

• The export method takes a EcdsaKeyExportConfig(EddsaKeyExportConfig) object as an argument.
  • keyshare: The client's share of the MPC wallet.
• privateKeyHex: The expored private key in hex format.
