Diffie – Hellman algorithm is very simple but operates with very big numbers. Thus, the main complexity for its implementation is the creation of the entity, which can perform arithmetical operations over these big numbers. Web1 day ago · depends on the language and the level of security required. If cryptographically strong random numbers aren't required then just use the standard rand() function. For strong cryptographic numbers in C++ just use the header. Otherwise in C use Windows-specific functions like rand_s() or BCryptGenRandom() – phuclv
