Dear Customer: I work as a C++ software developer for 5 years. I worked with corporate security systems, forensics development, encrtyption/decryption . I guarantee to do my best, because I am interested in successful completion of the task=) Thank you. Sincerely, Artem Brazhnikov, Senior C++ Software Developer

Hello I'm interesting your project very well I'm a Good C++, Java, Crypt, Math, Algorithm expert. I m quite well experienced in these jobs. Let's go ahead with me I want to service for you continously. Thanks

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, 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.

Hello, how are you? I have over 10 years experience in C/C++. And I have also 5+ years experience in ios app development. So that I think I can delivery the best result. Don't worry about quality and deadline. I want to discuss about your job in detail. Best regards, Jin

I have good experience using C++, even the C++ 11 standard. I have no experience in developing for IOS, I do not even have the tools to develop for this system, but I could do the work under Linux or Windows. I do not have working experience with DRM and cryptography, but I think I could manage to acquire it. Regards Ciro

I have already wriiten a cross platform (Windows, Linux, Mac) C++ licensing library. The code is tested and runs in production. The cryptographic library used is Botan. I will provide you with the functions with source code with running sample. Some of the functions: Algos: Sha256, AES-128/CBC, RSA 2048 Bit string LexRandomString(int length ); string LexEncrypter(string &plainText); bool LexFileEncrypter(STRING &filePath, string &data); string LexDecrypter(string &encryptedText); string LexFileDecrypter(STRING &filePath); string LexHexHash(string data); string LexHexEncode(string data); string LexHexDecode(string data); bool GenerateRSAKeyPair(string &privKey, string &pubKey); bool LexRSAVerifier(string &hash, string &signature, string &pubKey); string LexRSASigner(string &hash, string &privKey, string passphrase); bool LexRSAEncrypter(string &data, string &pubKey, string &encData); bool LexRSADecrypter(string &data, string &privKey, string &hexKey, string &passphrase);
