createKeyPairFromBytes

createKeyPairFromBytes(bytes, extractable?): Promise<CryptoKeyPair>

Given a 64-byte Uint8Array secret key, creates an Ed25519 public/private key pair for use with other methods in this package that accept CryptoKey objects.

Parameters

Parameter	Type	Description
`bytes`	`ReadonlyUint8Array`	64 bytes, the first 32 of which represent the private key and the last 32 of which represent its associated public key
`extractable?`	`boolean`	Setting this to `true` makes it possible to extract the bytes of the private key using the `crypto.subtle.exportKey()` API. Defaults to `false`.

Returns

Promise<CryptoKeyPair>

Example

import fs from 'fs';
import { createKeyPairFromBytes } from '@solana/keys';
 
// Get bytes from local keypair file.
const keypairFile = fs.readFileSync('~/.config/solana/id.json');
const keypairBytes = new Uint8Array(JSON.parse(keypairFile.toString()));
 
// Create a CryptoKeyPair from the bytes.
const { privateKey, publicKey } = await createKeyPairFromBytes(keypairBytes);
