Is it safe to use the Hash Generator online?

Yes — and ours is safer than most. Many free online tools quietly upload your files to their servers to do the work. We don't. Everything happens inside your browser on your own device, so your files never reach the internet. There's no upload step, no server copy, and no way for us (or anyone else) to see what you're working on.

Are my files uploaded to a server?

No. There's no server-side processing here. The whole tool is a tiny app that runs in your browser — we don't even have a server that could receive your files. You can confirm this by opening your browser's network tab while you use the tool: nothing leaves your device.

Do I need to sign up or pay?

No. There's no account, no email collection, no credit card. The tool is free to use as much as you want, on as many files as you want. We're supported by a few unobtrusive ads on the page — not by your data.

Why is MD5 listed if it's broken?

Many systems still use MD5 for non-security checksums (file integrity, ETags). For anything security-related, use SHA-256 or higher.

How do I hash a file instead of text?

File hashing is on the roadmap. For now, paste the file contents as text.

No. Hashing happens in your browser. We don't have a server.

Hash Generator (MD5, SHA-1, SHA-256, SHA-512)

Generate cryptographic hashes for any text. SHA family via the browser's Web Crypto API; MD5 from a small bundled implementation for legacy compatibility.

Features

Four algorithms at once: MD5, SHA-1, SHA-256, SHA-512
Web Crypto API for SHA — fast and standards-compliant
Updates live as you type
Copy any digest with one click
Marks MD5 and SHA-1 as broken for security (use SHA-256+ for new applications)

How to hash generator (md5, sha-1, sha-256, sha-512)

Type or paste — Drop in any text — short string, paragraph, JSON, base64.
Read the hashes — All four digests update live in the panel.
Copy — Click Copy on whichever hash you need.
