Does anybody know what is that:
document.sendin.password.value = hexMD5('\267' + document.login.password.value + '\131\273\022\212\207\357\340\346\135\276\211\344\041\307\011\116');

-i saw this interesting script and i want to know how this method work, when i refresh site all this numbers are changing-every time! Does anybody see this script somewhere, and know, how this script work???
I tryed to search over the internet but no result.

it's what could be called

a clientside encryption, using a randomly salted MD5, used to prevent eavsedroppers to intercept the password easily.

The salt is only marginally effective, since all one has to do to get the salt is to listion to the initial transfering of the page,

however it does defeat any listing like rainbowtables, from being effective.
