👉 Dummel is a mathematical concept in cryptography that refers to the process of converting two or more messages into one, so that each message can be uniquely deciphered. The key point about dummels is that they are not reversible and cannot be reversed; if one dummel was used on two messages, then both would have been decoded as the original messages. For example, suppose Alice sends a message to Bob using a dummel cipher. If Alice's dummel is "Hello
