About this tool
A hash is a fingerprint for data, and this checker produces one for text you type or for a file you choose in the browser. It uses the platform Web Crypto functions, so the work happens on your own device and the file is never uploaded. If the crypto functions are unavailable, it says so plainly instead of inventing a result.
Frequently asked questions
Is the file uploaded anywhere?
No. The file is read and hashed locally by Web Crypto, and it never leaves your device.
Why would hashing be unavailable?
Some restricted contexts do not expose Web Crypto. In that case the tool reports the gap instead of showing a fake hash.
