Encryption with ElGamal

Almost every working day, I have the privilege to work in a place that once hosted one the greats: John Napier. It was John who discovered logarithms, and showed that g^a times g^b is g^(a+b), and that g^a divided by g^b is g^(a-b). In our modern world, we use this type of method so often in our cryptography implementation, and it often provides the core around privacy-enhancing methods (such as with Zero-Knowledge Proof and Anonymisation).
