Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes online for free — live as you type, entirely in your browser. Nothing is uploaded.
100% private — runs entirely in your browser. Your files never leave your device.
SHA hashes use your browser’s built-in Web Crypto; MD5 is included for legacy checksums. Note that MD5 and SHA-1 are not secure for passwords or signatures. Everything is hashed locally — your text is never uploaded.
How to use the Hash Generator
- Type or paste your text.
- Pick MD5, SHA-1, SHA-256 or SHA-512.
- The hash updates live.
- Copy the digest.
What you can use it for
- Create checksums to verify data
- Generate SHA-256 hashes for integrity checks

Which hash algorithms are supported?
MD5, SHA-1, SHA-256 and SHA-512. SHA hashes use the browser's built-in Web Crypto; MD5 is included for legacy checksums.
Are MD5 and SHA-1 secure?
No — they're fine for checksums and non-security uses, but don't use them for passwords or digital signatures. Prefer SHA-256 or SHA-512.
Is my input uploaded?
No — hashing runs entirely in your browser, so it's safe for sensitive strings.
Can I hash a file?
This tool hashes text. For file checksums, paste the text content or use a dedicated file-hashing utility.
