    I have stumbled on unsolvable problem for me. My employer set me a task to decrypt URLs from a website.
    This is sample URL: http://hiderefer.org/?http://www.ce...7av-core-2-duo-24-4gb-320gb-dvd-dl-hd-3430-17. The links to the stores (with logos) under product are the ones that are encrypted.

    When I click on the encrypted URL, I get redirected to affiliate site. The deeplink of the affiliate site (page) is encrypted in
    original URL as "deeplink". I would like to extract this target URL from original, encrypted URL.

    Till now I figured out these details:
    The encyription starts after "deeplink=".
    It seems that encryption is probably some form of Base64 + something.
    All encrypted links start with the same string, also the strings on the links to the same domain are the same for more characters in a row.
    It seems that encrypted strings start with the "www." (except the one that links to IP).

    I have also attached an CVS of encrypted and target URLS.

    Please help!
