Quick Check is a small MD5 comparison program, that uses a class provided by "IranianExperts". At this point in the project it just compares MD5 however in the future it might support SHA1 and others. When you first open the program you are greeted with a small form that contains two text boxes and one button. First you enter the hash of the file you got from where you downloaded, next click the button and browse to the downloaded file and the program will retrieve the MD5 hash and compare. If they match, the label at the bottom left will let you know, same on the contrary. Please read the README after you download this as it contains some decent info as well. Thank you!
It refuses to check a file if you don't input a checksum! It does what it says but unfortunately only for MD5 check sums and I had some kind of copy paste bug.
