Hash Generator

Generate SHA-1, SHA-256, SHA-384, and SHA-512 checksums for text or files, computed on your device with the browser's Web Crypto API. Nothing is uploaded.

Text to hash

Drop a file
or click to browse (any type, any size)

Files never leave your browser. Nothing is uploaded.

Verify against a known hash (optional, paste an expected checksum)

Why no MD5? The browser's Web Crypto API doesn't include MD5 (it's cryptographically broken). For integrity and security use SHA-256 or stronger, it's the recommended default here.

About Hash Generator

Hash Generator is a free, private browser tool by Digital Heroes. It computes SHA-1, SHA-256, SHA-384, and SHA-512 checksums for any text or file, using the browser's built-in Web Crypto API. Everything runs locally on your device. Your files are never uploaded to any server. No sign-up, no installation, and no usage limits. The tool also works offline once the page has loaded.

What you can do

Hash any text instantly as you type, with live updates across all four algorithms.

Hash any file (any type, any size) by dropping it onto the page or clicking to browse.

Compare against a known checksum to verify a file or string has not been tampered with.

Copy any hash with one click: SHA-1, SHA-256, SHA-384, or SHA-512.

Track file progress with a visual progress bar during large file reads.

Run the tool offline: once loaded, no internet connection is needed.

How to use Hash Generator

Open Hash Generator in your browser. No signup or install required.

Choose the Text tab to paste or type text, or the File tab to drop or browse for a file.
