Key Pair

The key pair API has been redesigned. Key pairs are now managed using the Web Crypto API via the AsymmetricKey and createAsymmetricKeyPair utilities in @authup/server-kit.

The old useKeyPair, createKeyPair, and deleteKeyPair functions no longer exist.

createAsymmetricKeyPair

Creates an asymmetric key pair using the Web Crypto API.

Type

declare function createAsymmetricKeyPair(
    options: AsymmetricKeyPairCreateOptionsInput
) : Promise<CryptoKeyPair>;

Example

import { createAsymmetricKeyPair } from '@authup/server-kit';

(async () => {
    const keyPair = await createAsymmetricKeyPair({
        name: 'RSASSA-PKCS1-v1_5',
        hash: 'SHA-256',
    });

    console.log(keyPair);
    // { privateKey: CryptoKey, publicKey: CryptoKey }
})();

AsymmetricKey

A wrapper class for CryptoKey that provides PEM encoding and import utilities.

import { AsymmetricKey } from '@authup/server-kit';

// Import from base64-encoded key
const key = await AsymmetricKey.fromBase64({
    format: 'spki',
    key: base64PublicKey,
    options: {
        name: 'RSASSA-PKCS1-v1_5',
        hash: 'SHA-256',
    },
});

// Convert to PEM
const pem = await key.toPem();
