Free Online Hash Generator

A free hash generator creates MD5, SHA-1, SHA-256, and SHA-512 digests from any text instantly. Paste text and copy each hash — no signup, fully client-side with Web Crypto for SHA and a small local MD5 implementation.

Enter any text and get MD5, SHA-1, SHA-256, and SHA-512 hashes at once. SHA digests use the browser Web Crypto API; MD5 uses a small bundled implementation since Web Crypto does not support it. Copy each hash with one click. Free, no signup, nothing leaves your device.

MD5
SHA-1
SHA-256
SHA-512

Runs 100% in your browser. Your data never leaves your device.

SHA-1, SHA-256, and SHA-512 use crypto.subtle.digest from the Web Crypto API. MD5 uses a small local JavaScript implementation because Web Crypto does not support MD5. Everything runs in your browser with no server calls.

How to Use Hash Generator

  1. Type or paste any text in the input box
  2. MD5, SHA-1, SHA-256, and SHA-512 hashes appear instantly
  3. Click Copy next to any algorithm to copy that digest
  4. Edit the text and all hashes update automatically

When Would You Use This?

Developers verifying a downloaded file’s checksum paste the published SHA-256 and compare it to a local digest without installing openssl or hashing GUIs.

Security learners explore how tiny input changes produce completely different digests across MD5 and modern SHA algorithms side by side.

Backend engineers quickly hash API tokens or config strings while debugging — without sending secrets to an online hasher.

Frequently Asked Questions

Is this hash generator free to use?
Yes, completely free. No signup, no login, no payment ever.
Do I need to create an account?
No account needed. Open the tool, paste text, and copy the hashes.
Is my data safe?
Everything runs in your browser. Your text is never uploaded to our servers. We cannot see what you hash.
Which algorithms are supported?
MD5, SHA-1, SHA-256, and SHA-512. All four are computed at the same time from your input.
Is MD5 still secure?
MD5 is fine for non-security checksums and legacy systems, but it is not collision-resistant. Prefer SHA-256 or SHA-512 for integrity and security-sensitive checks.
Does this work offline?
Yes. Once the page has loaded, hashing works fully offline.
