On Mac OSX Leopard PowerPC, if I do: echo "hello" | md5
on the command line, the result is: b1946ac92492d2347c6235b4d2611184
But if I enter hello into one of the online md5 hash sites like http://md5online.net/ , I get: 5d41402abc4b2a76b9719d911017c59...

Try doing
echo -n hello | md5.
The text you enter in a website doesn't have a newline .
When you echo from the command line, md5 is calculating the sum of 6 characters - h,e,l,l,o plus newline.

I get the same value as that web site for the word "password":

I am trying to input a text file that contains MD5 hashes and keywords (one per line) into a C# app. Is there a way to check if a string is an MD5 hash? I looked on MSDN and couldn't find anything in the MD5 class.

Well, an MD5 hash is really just binary data - if you've got a string then it's presumably encoded, but not 100%
A MD5 hash is a 128 bit value.

For each of our binary assets we generate a MD5 hash. This is used to check whether a certain binary asset is already in our application. But is it possible that two different binary assets generate the same MD5 hast. So is it possible that two different...

Yes of collisions.
See this and this questions for examples.
Chosen strings having the same MD5 hash is very low.

Call getInstance("MD5") to get an MD5 message digest you can use.

There is a couple scripts out there on the internet to create an MD5 Hash.
While there are JS implementations of the MD5 algorithm, it is not possible for javascript to read files on the filesystem.

I am taking the MD5 hash of an image file and I want to use the hash as a filename.
How do I convert the hash to a string that is valid filename?
EDIT: toString() just gives "System.Byte[]"

System.Convert.ToBase64String
As a commenter pointed out -- normal base 64 encoding can contain a '/' character, which obivously will be a problem with filenames .
