Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 and more.

Enter your text below to generate a hash. Useful for checksums, data integrity verification and non-sensitive hashing needs.

Enter text to hash 0 characters

Hash algorithm

Convert to lowercase

Important Note

Hashing is a one-way process. You cannot reverse a hash to get the original text. Hash functions like MD5 and SHA-1 are not suitable for password storage — use a modern password hashing algorithm such as bcrypt, Argon2 or PHP's password_hash() instead.

When to use a hash?

Verify file integrity (checksums)
Detect if data has been modified
Compare large files efficiently
Generate content-based identifiers
Create non-reversible representations of data

Hash Examples

Here are some examples of generating hashes in different languages.

<?php
$text = "Hello World!";

// Generate different hashes
echo "MD5: " . md5($text) . "\n";
echo "SHA-1: " . sha1($text) . "\n";
echo "SHA-256: " . hash('sha256', $text) . "\n";
echo "SHA-512: " . hash('sha512', $text) . "\n";

const data = new TextEncoder().encode("Hello World!");
const digest = await crypto.subtle.digest("SHA-256", data);
const hex = [...new Uint8Array(digest)]
  .map(b => b.toString(16).padStart(2, "0")).join("");
console.log(hex);

import hashlib

text = "Hello World!".encode()
print("MD5:", hashlib.md5(text).hexdigest())
print("SHA-256:", hashlib.sha256(text).hexdigest())

const { createHash } = require('node:crypto');
const text = "Hello World!";

for (const algorithm of ['md5', 'sha1', 'sha256', 'sha512']) {
  console.log(algorithm + ': ' + createHash(algorithm).update(text).digest('hex'));
}

using System;
using System.Text;
using System.Security.Cryptography;

byte[] data = Encoding.UTF8.GetBytes("Hello World!");
Console.WriteLine("MD5: " + Convert.ToHexString(MD5.HashData(data)).ToLowerInvariant());
Console.WriteLine("SHA-1: " + Convert.ToHexString(SHA1.HashData(data)).ToLowerInvariant());
Console.WriteLine("SHA-256: " + Convert.ToHexString(SHA256.HashData(data)).ToLowerInvariant());
Console.WriteLine("SHA-512: " + Convert.ToHexString(SHA512.HashData(data)).ToLowerInvariant());
