Online MD5 Hash Generator

I'm trying to create a batch script that runs certutil -hashfile MD5 on each file in a folder and write the output to a file.

I have this code below except it only works on the files in the current folder,I would like it to work such that when a folder is drag-dropped into the batch file .bat it processes that folder only.

for %%a in (*) do certutil -hashfile %%a MD5 >> MD5_log.txt

Also is there a way to get it to output spaces in the log file between iterations of the certutil output text?

Whenever I try to run the above mention command it shows the following error.

This is the first step when i try to run the simple bundle command: Bundle install

And when i found the above error i try to run the server command for the rails but it doesn't work out for me.

rails server

Is there anything I am missing out.

How to write functionForGenerateMD5hash for this code? I already have fileVideo and I need to send md5 hash of this file to server by clicking button.

$("#someButton").click(function() {var fr = new FileReader();      fr.onload = function(e) {                string md5 = functionForGenerateMD5hash(e.target.result);    // send md5 here};       fr.readAsArrayBuffer(fileVideo);

I want to use batch to upload from the mput command to FTP. But, what I do not want to do is upload a file that has already been uploaded before, so I need the MD5 of each file and compare the new ones with the existing ones.

How are the commands I need?

I wonder how reliable the adler32 checksum is, compared to e.g. md5 checksums? It was told on wikipedia that adler32 is "much less reliable" than md5, so I wonder how much, and in which way?

More specifically, I'm wondering if it is reliable enough as a consistency check for long-time archiving of (tar) files of size 20GB+?
