login typo3

Its not found in the md5.js (doChallengeResponse). I am looking now in init.php and template.php. I guess it will be in some of the included files I will see in init.php. In this file are included some php classes and I guess somewhere is the java script.

I guess I found it:

function doChallengeResponse(superchallenged) { //
password = document.loginform.p_field.value;
if (password) {
if (superchallenged) {
password = MD5(password); // this makes it superchallenged!!
}
str = document.loginform.username.value+":"+password+":"+document.loginform.challenge.value;
document.loginform.userident.value = MD5(str);
document.loginform.p_field.value = "";
return true;
}
}
