Cách sử dụng
The word 'cipher' can refer to a person who has no power or is not important in a situation, or it can refer to a code or code system used to keep information secret. For example, when someone is not important in a situation, you may say they are a 'cipher'. For instance, a new employee in a big company might feel like a 'cipher' because they haven't met many people yet and don't have much influence.When someone mentions a 'cipher' in terms of a code, they are usually talking about a message written in code that only certain people can read. For instance, during the World Wars, countries used cipher machines to encrypt important messages so that enemy forces couldn't intercept and read them. This made the messages unreadable to anyone who didn't know the cipher. So, if you hear the word 'cipher', it could be referring to someone who is not important or to a code used to keep information secret.
