🔐 Password Utilities

import { encryptPassword, comparePassword } from "kasukabe-auth-core";

const hash = await encryptPassword("my-secret-password");

// Compare plaintext with hashed password
const isValid = await comparePassword("my-secret-password", hash);

🔑 JWT Token Utilities

const access = generateAccessToken(user.id);
const refresh = generateRefreshToken(user.id);

Requires these environment variables:

ACCESS_SECRET=your_secret_key
REFRESH_SECRET=your_refresh_secret

🌐 Google OAuth Utilities

import { getGoogleAuthUrl, getGoogleUser } from "kasukabe-auth-core";

// 1. Redirect to Google login
const url = getGoogleAuthUrl();

// 2. After redirect, exchange code for user info
const userData = await getGoogleUser(code);

Requires:
