SHA256 Generator

What is SHA256 Generator?

A Hash Generator is a cryptographic tool that converts any input text or data into a fixed-size string of characters, known as a hash or digest. This process is one-way, meaning the original data cannot be reconstructed from the hash, making it ideal for verifying data integrity, storing passwords securely, and creating digital signatures. Our tool supports a wide range of algorithms including the industry-standard SHA-256, the legacy MD5 (for non-security use), SHA-512 for higher security, and others like SHA-1, SHA-384, and RIPEMD-160. Unlike server-side tools that require you to upload your data, this generator runs 100% in your browser using the Web Crypto API. This guarantees that your sensitive information, passwords, or confidential documents never leave your device, providing maximum privacy and security. Whether you are a security professional verifying file checksums, a developer testing authentication systems, or a student learning about cryptography, this tool offers a fast, secure, and offline-capable solution.

Code Examples

async function sha256(message) { 
  const msgBuffer = new TextEncoder().encode(message); 
  const hashBuffer = await crypto.subtle.digest('SHA-256', msgBuffer); 
  const hashArray = Array.from(new Uint8Array(hashBuffer)); 
  return hashArray.map(b => b.toString(16).padStart(2, '0')).join(''); 
 } 

import hashlib

text = "Hello World"
hash_object = hashlib.sha256(text.encode()) 
print(hash_object.hexdigest())
