Create tool to generate valid shsh blob for 5.1.1 ios

We need an application which runs on Windows that can be used to generate valid shsh blobs for iOS 5.1.1 restores. The generated blobs will then be used in the IPSW-stitching process (you don't have to worry about this), and finally restored on a device. The keys required to generate this blob can be user-input via input boxes provided by your application, or otherwise they can be extracted automatically by having the device plugged into the USB port (similar to how TinyUmbrella does it).

We understand this is mostly a cryptography problem - therefore we are looking for people with experience in this area.

Upon being award this project, the selected candidate should be prepared to present a proof-of-concept (video or design logic diagram) before the first installment of 50% will be awarded. Upon receiving a working-beta application, we will award an additional 40% and the remaining 10% will be awarded on final approval.

This project will strictly be carried out on Freelancer - hence please don't ask for my skype id or whether we can perform payment using PayPal. If you have questions, please post them on this page. A successful bidder should be able to complete this project within 30 days, and have reputable references (not blank references like I've seen too many of). Furthermore, the successful bidder should send me a private message illustrating exactly how they plan to pursue this; what is the general direction you plan to take. Please don't send me a list of all your past ipa projects, or links to see some websites you've created in the past. Unless its cryptography related, the link or reference will be ignored.

Finally, if you prefer to write this application to target the MacOS, that will be fine. Please be clear, we don't want an ipa for the device. We want an application that runs on a traditional desktop computer (or notebook, or laptop, or server, or "whatever" you want to call them, just not .ipa, can even be a package for Linux distribution)
