It's not a cryptographic algorithm. In the very strictest sense, ASCII could be considered a substitution cipher (it replaces a character with a number), but it's just a representation, and is not done to protect information. Sorry, but you're using the word incorrectly. If you intend to seek formal education on the topic, you should start using (and spelling) the words properly. Arguing with me about the meaning of words is just a silly waste of both our time; I know more about this topic than do you.TsunamiJoe said:as i said you cannot translate it efficiently, and secondly you can form a cryptographic algorithym to translate them into machine code, which is what the machine does
Again, this is not encryption. You seem to think that any kind of protection mechanism is cryptography, but that's just simply not true.for instance when sending data through the ports, you can protect the port by not allowing access into it, which is done often through authorization strictly between machines without users knowing it
Viruses tack executable code onto executable programs. In order for a virus to infect a file as its bytes are being sent across the network, the virus would have to interact with both peers on the network, performing a very elaborate middle-man attack, crafting new packets with the right sequencing information to maintain contuinity for the duration of the connection.Could you perhaps reiterate this? But if your saying what I think you are, then its the same way that someone would intercept an encrypted message before it gets to one of the users, just its done by more or less random from a person's computer which he has initiated a program in to spread a virus. But again I could just be reading that wrong, and just to declare a network to me is a connection between any 2 or more machines whether it be person to server, person to person, or sever to person.
As far as I know, it's never been done, and viruses do not infect files as they are being transferred byte-by-byte across the network. If you do not have references to such viruses, you shouldn't be saying such things happen.
