March 08, 2016

The Web Crypto API is an interface allowing a script to use cryptographic primitives in order to build systems using cryptography. A fundamental feature of this API is to allow the manipulation and storage of private and secret keys without the underlying bits of the key to be available to JavaScript.

This is html5 file hash online calculator, which supports an unlimited number of files and unlimited file size. Your files are not transferred to the server. All calculations are performed directly in the browser.
