Hi Ilya,

Could you post how you're using CryptoJS to checksum the file? I'd like to add 
it to our test suite.

hi,

I use the File API (http://www.w3.org/TR/FileAPI/), you can find it here: 
http://www.md5file.com/calculator/

This is my project, which calculates the MD5, SHA1, SHA256 hashes based on your 
library.

I have already applied a patch to fix the problem there.
