You probably know about Google's PageRank and if you don't:
PageRank Technology: PageRank performs an objective measurement of the importance of web pages by solving an equation of more than 500 million variables and 2 billion terms. Instead of counting direct links, PageRank interprets a link from Page A to Page B as a vote for Page B by Page A. PageRank then assesses a page's importance by the number of votes it receives.


I was reading the source code of a perl script that uses the PageRank package(PageRank =>google pagerank of page) writeen by Yuri Karaban until I come to the line that shows the query string. Something like:

search?client=navclient-auto&ch=' . $ch . '&ie=UTF-8&oe=UTF-8&features=Rank&q=info:' . uri_escape($url);

Try It. I can't resist the temptation to try the query in the FireFox browser with http://www.yahoo.com as url and a random number as $ch. I expected to get an error.



But not that error ! and what was really inexpected is that Google wants me to send a code that looks like a PGP signature :-). Look at the picture.



I have no idea what this code hides. I really want to know what the real message is.

If you know something about this code, send a comment.
