I am very proficient in c, c++. I have 15 years c++ developing experience now, and I have worked for 5 years. My work is online game developing, so I am very familiar with crypto, and mainly focus on server side, the language is c++ under linux. I used c++ to make many great projects, for example, I made the tools which can convert java files to c++ scripts which has the same effect, of course garbage collection included. I also made our own mobile game using c++, I even can show you the demo of client. Trust me, please let expert help you.

Hi, After reading the file attached that descripts the requirements, I have some questions in order to get you the optimal implementation. If I got the idea of your instructor, he/she needs the project to be done as below: On each party: 1. Select a random key for AES. 2. Create a Hash key by SHA1 for the above key. (data integrity) 3. Generate 2 keys for RSA (public and private keys), and sign the Hash key. (data signing) 4. Send the AES key, signing result (signature) and RSA keys to the another party as well as decrypted data (file or string). When Another Party Receives Data, does: 1. Generating a Hash key for the received AES key. 2. Verifying the received signing (signature) by comparing with a temporary signature we create using the received RSA keys for the above hash key. 3. If the signature is correct then we will decrypt the received data (file or string) by the received AES key. Please ask your instructor if this what looks for, or he/she needs another path. Best Regards
