Hi there,

This webapp lets you calculate the MD5, SHA1, SHA256 hash and CRC32 checksum for files right in your browser.

Simply select or drag & drop the file you wish from your desktop, download bar or folder and it will be processed immediately.

You can also create shareable validation links from your calculated hashes using the link buttons.

Files are not sent to a server. Hashing is done through JavaScript with asm.js or PNaCl native acceleration if available.
