Frequently Asked Questions
What is a Hash Generator?
Need to verify a file download hasn't been tampered with? Or check that an API response is genuine? A hash generator takes any input (text, password, file) and produces a fixed-length fingerprint. Change even one character and you get a completely different hash. This tool computes MD5, SHA-1, SHA-256, and SHA-512 hashes right in your browser. Nothing ever touches a server.
Which Algorithm to Pick
MD5 is fast but cryptographically broken, so only use it for non-security checksums. SHA-1 is also compromised (Google proved a collision in 2017). SHA-256 is the current standard for TLS, Bitcoin, and code signing. SHA-512 gives you extra security margin and is actually faster on 64-bit systems. For passwords, none of these alone is enough. Use bcrypt, scrypt, or Argon2 in production.
Verifying File Downloads
Software publishers post SHA-256 checksums next to downloads. Grab the file, upload it here, generate the hash, and compare. If even one character differs, the file was corrupted or tampered with. The built-in comparison field does this automatically so you don't have to eyeball 64 characters.
Privacy First
All hash calculations use the browser's native Web Crypto API. Your text, passwords, and files never leave your device's memory. That makes this safe for hashing sensitive stuff like API keys, passwords, and confidential documents.
