Hash Generator

Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 and HMAC hashes for any text or file. 100% browser-side via Web Crypto API. No upload, no signup.

✅ Free access 🔒 No Signup ⚡ Browser processing 🌐 Browser Based

Quick Answer

The Hash Generator computes MD5, SHA-1, SHA-256, SHA-384, SHA-512 and HMAC hashes for any text or file you provide. Uses the browser's Web Crypto API — your data never leaves your device. Useful for checksum verification, signing payloads, content addressing and password derivation prototyping.

Frequently Asked Questions

Everything you need to know about Hash Generator

Which hash algorithms are supported?

MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — plus HMAC variants of each SHA algorithm (HMAC-SHA-256, HMAC-SHA-512, etc.). SHA-3 (Keccak) is on the roadmap.

Should I still use MD5?

Only for non-cryptographic uses like checksums or cache keys — MD5 is considered broken for security (collision attacks demonstrated in 2004). Use SHA-256 or stronger for password storage, signatures or content addressing. We keep MD5 because it's still useful for verifying file integrity against legacy systems.

Is my file uploaded when I hash it?

No. File hashing uses the browser's File API to read the file into memory locally, then the Web Crypto API to compute the digest. Nothing ever leaves your device. You can verify by checking your network tab — there are zero requests during hashing.

What's the difference between a hash and an HMAC?

A plain hash is a one-way function of just the input. HMAC adds a secret key — only someone with the key can produce the same HMAC for the same input. HMAC is used for message authentication (proving the message came from someone who knows the key), while plain hashes are used for integrity (proving the message hasn't changed).

Why are MD5 and SHA-1 in the same tool as SHA-256?

Different use cases. Verifying an old SHA-1 checksum from a 2015 release notes page is a legitimate use. Signing a JWT is not — for that, use SHA-256 minimum. We label them but don't gate them, so you have the tool you need either way.
