Hash Generator (MD5 & SHA)

Compute MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text at once — instantly and privately in your browser.

🔒 Runs entirely in your browser — nothing you type is uploaded or stored on a server.

The Hash Generator turns any text into its cryptographic hash — a fixed-length fingerprint that changes completely if even one character of the input changes. Type or paste your text and it computes MD5, SHA-1, SHA-256, SHA-384 and SHA-512 all at once, updating live as you type, each with its own copy button. It's the quick way to produce or verify a checksum without installing command-line tools.

Developers reach for hashes constantly: to verify a file or message wasn't altered, to compare a value against a known checksum, to generate cache keys and content fingerprints, or to check a string against an expected digest. The SHA family here is computed with the browser's built-in Web Crypto implementation, so the results match what you'd get from sha256sum, OpenSSL or your language's standard library — byte for byte.

Everything runs in your browser. The text you hash is never uploaded, which makes it safe for hashing tokens, secrets or private strings you'd never want to paste into a remote service. A quick note on security: MD5 and SHA-1 are included for compatibility and checksums but are considered broken for security — use SHA-256 or stronger when integrity really matters, and never store passwords as a plain fast hash.

How to use

  1. Type or paste the text you want to hash into the box.
  2. Read the MD5, SHA-1, SHA-256, SHA-384 and SHA-512 digests — they update instantly as you type.
  3. Toggle “Uppercase hex” if you need the hash in capital letters.
  4. Click Copy next to any hash to grab just that one.
  5. Compare the value against an expected checksum to verify integrity.

Examples

Verify a checksum
Paste a value and compare its SHA-256 against the checksum published next to a download to confirm the text matches.
Content fingerprint
Hash a block of text to get a short, stable SHA-256 key for caching or de-duplication.
Match a stored digest
Check whether a string produces the exact MD5 or SHA-1 a legacy system expects.
Spot a tiny change
Hash two nearly identical strings and watch the digests come out completely different — proof that hashing detects the smallest edit.

Frequently asked questions

Which hash algorithms does this support?
Five at once: MD5, SHA-1, SHA-256, SHA-384 and SHA-512. The SHA family is computed with your browser's built-in Web Crypto engine, so the output matches standard tools like sha256sum and OpenSSL exactly.
Is my text uploaded to a server?
No. All hashing happens in your browser with JavaScript and the Web Crypto API, so the text you enter — even tokens or secrets — never leaves your device.
Should I use MD5 or SHA-1 for security?
No. Both are cryptographically broken (practical collisions exist) and should only be used for non-security checksums or compatibility with older systems. For anything security-sensitive, use SHA-256 or SHA-512.
Can I hash a password with this?
You can compute a hash, but a single fast hash is not how passwords should be stored. Real password storage uses a slow, salted algorithm such as bcrypt, scrypt or Argon2. This tool is for checksums and fingerprints, not password databases.
Why do MD5 and the SHA hashes appear at slightly different moments?
MD5 is computed synchronously in JavaScript, while the SHA hashes use the browser's asynchronous Web Crypto API. Both are effectively instant; the SHA values simply resolve a fraction of a moment later.
Do the SHA hashes need an internet connection?
No, but they do need a secure page — the Web Crypto API is available on HTTPS sites (and on localhost). On txtset.com, which is served over HTTPS, all five hashes work fully offline once the page has loaded.
