100% private — runs in your browser

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

  1. Type or paste your text.
  2. Pick MD5, SHA-1, SHA-256 or SHA-512.
  3. The hash updates live.
  4. Copy the digest.

What you can use it for

  • Create checksums to verify data
  • Generate SHA-256 hashes for integrity checks
  • Compute MD5 for legacy systems
  • Hash text privately in your browser

Frequently asked questions

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.
