node-dpapi

Node native module to encrypt/decrypt data. On Windows, it uses DPAPI

API:

``typescript
function protectData(
userData: Uint8Array,
optionalEntropy: Uint8Array,
scope: "CurrentUser" | "LocalMachine"
): Uint8Array;

function unprotectData(
encryptedData: Uint8Array,
optionalEntropy: Uint8Array,
scope: "CurrentUser" | "LocalMachine"
): Uint8Array;
`

Example:

`javascript
import * as dpapi from "node-dpapi";

const buffer = Buffer.from("Hello world", "utf-8");

const encrypted = dpapi.protectData(buffer, null, "CurrentUser");
const decrypted = dpapi.unprotectData(encrypted, null, "CurrentUser");
``
