I am very new to cryptography so please help me out with this one

I have a Question Key-1 which + some encryption gives Answer key-1. I have to find the encryption to apply it to another Question key-2 to find the Answer key-2. Please tell me how to achieve it.

Question key -1

plus some encryption gives me,

Answer Key -1

Now I should find what encryption was used above, so that I can apply it to the key blelow

And find the Answer key-2.

9r33X8icy9lGaryZHyduWJ9nQRRPuUOnqJaoWqB9OMJT2yk2AZg61nqXyYbPMejw is first comment for both the question key 1 & 2. And just 9r33X8icy9lGaryZHyduWJ9nQRRPuUOnqJaoWqB9OM is common between question & answer. Hope this helps! :p – Cyril N. May 15 '12 at 17:34

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.

How do you get this problem? First, try to count the data size. If it's a one way encryption (hash), in theory you can't reverse the data.
