I've been looking at the various types of ciphers and I can't seem to find something I want or if it's even possible.
For example the text is "London2234", when run through the cipher, it encrypts into something like "Marble2234" where a person who doesn't have the cipher doesn't see it as garbage but sees it as another word where they can't make any context of.
Like a dictionary cipher of some sort? Is it possible?
