`extractable?`	`boolean`	Setting this to `true` makes it possible to extract the bytes of the public key using the `crypto.subtle.exportKey()` API. Defaults to `false`.

Returns

Promise<CryptoKey>

Example

import { createPrivateKeyFromBytes, getPublicKeyFromPrivateKey } from '@solana/keys';
 
const privateKey = await createPrivateKeyFromBytes(new Uint8Array([...]), true);
 
const publicKey = await getPublicKeyFromPrivateKey(privateKey);
const extractablePublicKey = await getPublicKeyFromPrivateKey(privateKey, true);
