Javascript & MD5 encryption

I want to encrypt a string with MD5 using Javascript. I have found two references, the first is

[js]
var encryptedstring=hex_md5("hello");
document.write(ecryptedstring);
[/js]

which doesn't work. The second is a massive javascript code located at

http://pajhome.org.uk/crypt/md5/index.html

which is quite impressive. Is there a simple Javascript md5() command similar to the PHP md5() command? If so, can you provide it with the correct syntax. Thanks.

IS that something you want?

Nope, this webpage calls another document (cipher.js) which is a long series of mathematical functions that alters a string into another encrypted string (according to the authors encryption scheme). I am looking for a single javascript command that returns the md5 checksum of a string - not extraneous pages of mathematical hex/binary rotations and conversions.

There is no hash function implemented in JavaScript. You will have to use that external js file.
