How to get the "EncryptKey" ?

[sofax222]

The twRO needs the storageEncryptKey !!
The storageEncryptKey is for the password of storaging !!

Then, if I want to buy some cash-items, it needs a password, too !!
Now, I have the cash-password and the packet content of the sending encryed password !
How can I get the EncryptKey of cash-shop ?

Debug the Client app, and find it there somewhere. (To be short).
