Usage

Using hashed token:

import verifyAuthResult from "@use-telegram-auth/server";
import { createHash } from "crypto";

const BOT_TOKEN = process.env.BOT_TOKEN;
const HASHED_BOT_TOKEN = createHash("sha256").update(rawBotToken).digest();

const result = verifyAuthResult(tgAuthResult, HASHED_BOT_TOKEN);

Using raw non-hashed token:

import { verifyFromRawBotToken } from "@use-telegram-auth/server";
