Somebody asked me the following, and I thought it better to show the answer to everyone:
Quote:
Hi,
I was looking at the checksum algorithm for Pagerank and I am trying to figure it out myself.

My question is how do you get the value for these variables?

var_8
var_4
url_offset
url_length
magic_dword
var_8 and var_4 are local stack variables. They are uninitialized at the beginning of the algorithm function.
url_offset is a pointer to the URL of the web site we want to check the rank for.
url_length is the length of the URL of the web site we want to check the rank for.
magic_dword is a static 32bit word being passed to the function. As shown in the code, it is 0xE6359A60.
