How It Works

Continuously type text into the input field to watch the tool generate hashes across all supported algorithms simultaneously in real-time. Alternatively, you can drag-and-drop or manually select a file from your computer to securely hash its underlying binary content.

Frequently Asked Questions

What is a cryptographic hash? ▾

A hash is a mathematically fixed-size string produced by running a one-way cryptographic function on any amount of data. The exact same input will always produce the exact same hash, but you cannot mathematically reverse a hash back to discover its original input.

Is my data and file content kept safe? ▾

Absolutely. All hashing computations are performed 100% locally inside your web browser leveraging the Web Crypto API. Absolutely no text or files are ever sent to our backend servers.

Why should I hash a file? ▾

Hashing a file generates a unique 'fingerprint' (checksum). You can compare this checksum against a provided trusted hash from a developer to mathematically verify that your downloaded file hasn't been corrupted or maliciously altered.
