What does password have to do with mathematics? My research topic is mathematics in cryptography, but I have never had a clear understanding of the relationship between cryptography and mathematics.
Quite simply, passwords are composed of numbers, which is the same thing. Besides, there are many theorems and definitions in mathematics. According to these, the password can be deduced by appropriate methods. In addition, setting passwords is also inseparable from mathematics. You must use your own mathematical thinking to come up with difficult passwords. Therefore, cryptography and mathematics are closely related.
