Cryptographic Hashing Made Simple Hashing is fundamental to software engineering — from password storage and data integrity verification to blockchain and digital signatures. Our hash generator uses your browser's native Web Crypto API to compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes with zero dependencies.
Why Use the Hash Generator? - Verify file integrity instantly - Compare checksums without leaving the browser - Generate cryptographic digests for security audits
Hash Comparison Mode Need to verify if two payloads match? Toggle Compare mode to instantly check if any generated hash matches a reference hash you paste in. Perfect for verifying file integrity, comparing checksums, or validating API webhook signatures.
Privacy First All hashing happens locally in your browser using the `SubtleCrypto` Web API. Your input text never leaves your machine — making this tool safe for hashing sensitive data like passwords, API keys, or proprietary content.
Example Usage
js
const text = "Hello World";
const hash = await crypto.subtle.digest('SHA-256', new TextEncoder().encode(text));
console.log(new Uint8Array(hash));
