Hi, I need a custom encryption/decryption algorithm which should be based on a 4 byte key (DWORD). The algorithm must be complicated enough to deter reverse engineering or at least make it hard. It should work in c++ and php i.e. encrypted data from a c++ program should be decrypt-able by php code. These are the c++ function prototypes (php ones are similar): void encrypt(vector<char>& buffer, DWORD key) void decrypt(vector<char>& buffer, DWORD key) Your submission must include a wide range of test cases to make sure the algorithm doesn't break.The algorithm has to be private, no open-source or publicly available algorithms will be accepted! Please include some details about the algorithm you intend to implement, pref. pseudo code. Thanks.

We are looking for a developer to write some code to Google API that will update the inventory in a Google shopping feed that is being updated from Yahoo Stores. The API needs to update the shopping feed no less than once an hour but preferably more often. If we can include other product attributes in the update, such as price and sale price, that would be good as well but the in stock/out of stock variable is the top priority. The feed is in English and the feed target language is English as well. Any other needed information can be provided upon request. I have attached a screenshot of where this piece of coding will be placed to give an idea of what we are looking for. We would like for this to be completed within 3 days. If you have any questions please send a message or submit your proposal below.
