Web12 apr. 2024 · The RSA Cryptosystem uses computations in Z n, where n is the product of two distinct odd primes p and q. For such integer n, we have Φ(n) = (p − 1)(q − 1). Here, we make use of prime numbers, their properties to get the enciphering modulus. Also, Euler’s Phi function is used to obtain n. WebNumber theory is famously completely useless. Gauss called it the queen of mathematics or the jewel of mathematics or something like that, because its only purpose is to further our understanding of itself . That said, solving number theory problems algorithmically is a good use of your time and effort. someone who is genuine
