Webcryptography is based on the following empirically observed fact (here written as if it were carved in stone): Multiplying two integers is easy, but finding a nontrivial factor of an integer is hard. In other words, integer multiplication is in practice a “one-way function.” If a number is large, it’s essentially impossible to factor it. 11 WebAn Introduction to Modular Math. When we divide two integers we will have an equation that looks like the following: \dfrac {A} {B} = Q \text { remainder } R B A = Q remainder R. For these cases there is an operator called the … trveadp
