Hi,
I have great experience in the design and implementation of several cryptographic algorithms from scratch in C/C++ for both Windows as well as Linux operating systems. I have great experience with the inner workings of both symmetric and assymetric methods of encryption. I have successfully implemented AES, in different modes, Salsa20 (a new age stream cipher) and many more. I have also implemented from scratch Elliptic Curve Cryptography with SECP256k1 .
I am very much familiar with ECDH and I believe I can definitely help you within the shortest time possible. I am also very good with the OpenSSL library!
I am really curious to know the exact details of your project. Please feel free to contact me via chat, so that we can start working on this amazing project immediately!
Best Regards,
Aravind A
