What is a Hash Generator?

🔐
Cryptographic Hashing
A hash function converts any input into a fixed-size string. The same input always produces the same hash instantly verifiable.
📦
File Integrity
Generate SHA-256 of any file and share the hash. Anyone can verify the file was not tampered with by comparing hashes.
🔑
Password Security
Websites store hashed passwords, never plaintext. When you log in, your input is hashed and compared to the stored hash.
🛡️
API Authentication
HMAC-SHA256 signs API requests so servers can verify requests have not been modified in transit.
⚡
Instant & Private
Uses the browser-native Web Crypto API. No server calls, no logging, no storage. Completely private.
🔍
Hash Comparison
Paste two hashes to instantly verify they match. Essential for file verification and security audits.
