Hash Generator
Generate cryptographic hashes (SHA-1, SHA-256, SHA-384, SHA-512) from text, computed locally in your browser.
How to use Hash Generator: Open Hash Generator — it runs entirely in your browser with no setup. Paste or type your input into the text area, or upload a file where supported. Set any options you need. The result appears in the output panel — there is no upload step and no waiting on a server. Everything runs inside your browser, so your data never leaves your device.

Hashes are computed locally with the Web Crypto API. MD5 isn't supported by browsers; use SHA-256 or stronger for security.
Generate cryptographic hashes (SHA-1, SHA-256, SHA-384, SHA-512) from text, computed locally in your browser. Hash Generator is a free, browser-based tool in the Filevane programming collection — there is nothing to install, no account to create and no watermark on your results. It works on desktop, tablet and mobile, and because the work happens on your own device it stays fast even with large inputs.
How to use Hash Generator
- Open Hash Generator — it runs entirely in your browser with no setup.
- Paste or type your input into the text area, or upload a file where supported.
- Set any options you need. The result appears in the output panel — there is no upload step and no waiting on a server.
- Review the output instantly; large inputs are handled locally without lag.
- Copy the result to your clipboard or download it. Your data never leaves the page.
Why use Hash Generator?
- 100% free with no limits, no sign-up and no watermarks.
- Private by design — your data are processed in your browser and never uploaded to a server.
- Fast and lightweight, with instant results even on a phone or a slow connection.
- Works everywhere — any modern browser on Windows, macOS, Linux, Android or iOS.
- Part of a full programming suite, so related hash tasks are one click away.
Is it private and secure?
Your privacy is built in. Hash Generator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.
Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.
You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.

Frequently asked questions
Which hash algorithms should I use?
SHA-256 for anything security-related. MD5 and SHA-1 are both cryptographically broken — MD5 collisions have been practical since 2004, and SHA-1 since the SHAttered attack in 2017 — so they remain useful only for detecting accidental corruption, never for verifying that a file has not been tampered with.
What is the difference between hashing and encryption?
Encryption is reversible with the right key; hashing is one-way by design. You cannot recover input from its hash — you can only hash a candidate and compare. That is why hashes verify integrity and store password verifiers, while encryption protects confidentiality.
Can I use a hash to store passwords?
Not a plain one. SHA-256 is deliberately fast, which is exactly what an attacker running billions of guesses per second wants. Password storage needs a deliberately slow, salted algorithm such as bcrypt, scrypt or Argon2.
Why does the same file give a different hash elsewhere?
Almost always a difference in what was hashed rather than in the algorithm: a trailing newline, CRLF versus LF line endings, or a text-mode read that rewrote bytes. Hashing the raw bytes of the same file always yields the same digest.
