Get Base64 encode file-data from Input Form
...ay (or it doesn't work), look at readAsArrayBuffer(). This will give you a Uint8Array and you can use the method specified. This is probably only useful if you want to mess with the data itself, such as manipulating image data or doing other voodoo magic before you upload.
There are two methods:

C++ performance challenge: integer to std::string conversion
...
Would it be difficult to modify it to work with uint64_t? I moved this code to C and replaced 'T' with int type and it works, but it doesn't work for uint64_t and I don't have a clue how to customize it.

Personally, I would just cast the values to unsigned long or long like another answer recommends. If you use C99, then you can (and should, of course) cast to unsig...
