Hash Generator for TypeScript Developers

Quick Answer

DevToolHQ's hash generator works great alongside TypeScript. Use it to quickly hash generator during development, then integrate the pattern into your TypeScript codebase using the code example below.

Use Cases in TypeScript

  • 1.Hash user passwords before storing in database
  • 2.Generate checksums for file integrity verification
  • 3.Create HMAC signatures for webhook validation
  • 4.Hash API keys for secure storage

TypeScript Code Example

TypeScript
import { createHash, createHmac } from 'crypto';

function sha256(input: string): string {
  return createHash('sha256').update(input).digest('hex');
}

function hmacSHA256(secret: string, payload: string): string {
  return createHmac('sha256', secret).update(payload).digest('hex');
}

// Verify webhook signature (Express handler)
import type { Request, Response } from 'express';
function verifyWebhook(req: Request, res: Response): void {
  const sig = req.headers['x-signature'] as string;
  const expected = hmacSHA256(process.env.WEBHOOK_SECRET!, req.body);
  if (sig !== expected) { res.sendStatus(401); return; }
  res.sendStatus(200);
}
