Hi,
I am new to encryption and have read a lot but still don't know what I'm doing. Just to clarify when using the keys is it just for a handshake between the client and server to allow access or does it affect the caesar cipher as well? because after looking at some examples I still don't have much of an idea.
I have seen many examples of caesar cipher encryption/decryption but none of them use a public/private key with it. I am supposed to use the key (randomised one) along with the caesar cipher but am not sure how to implement it.
For example if I had the outcome of a key of 32 would the client and server just say its okay to go ahead or would it affect the caesar cipher which I would have shifting by 1 as in a=b b=c c=d and a sample caesar value would be hppe for good. When encrypting from the client to the server do I just send 'hppe' after both the client and server agree on the key value of 32, or do I use the key value of 32 and change the caesar shifted value of hppe even more?
