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":

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 .

I have never checked and compared the MD5 hash to the real MD5 hash at programs homepages. Programs which I have downloaded have always worked.
Is it possible that someone can put their own code during downloading?

Thats all I think.
An MD5 hash is a form of validationFile can be checked if it is corrupted.

Hi all,
I need to hash (MD5) all the password in our Sql Server 2000 database. I can easily generate a C#/VB.NET program to convert (hash) all the passwords, but I was wondering (more for my education than for a real compelling need) if it was possible...

There is nothing magical about md5, you can implement it as a pure tsql function if you want to.
No, there is no native TSQL command to generate MD5 hash's in SQL Server 2000.

I'm looking to create a 32-bit hash of some data objects. Since I don't feel like writing my own hash function and md5 is available, my current approach is to use the first 32 bits (i.e. first 8 hex digits) from an md5 hash. Is this acceptable?

Alternatively you could also use CRC32 which should be much faster to compute (and the code .
In other words, are the first 32 bits of an md5 hash just as "random" as any other substring?
Yes of an MD5 hash.
