WebIn general, the larger the key size used in PGP-based RSA public-key cryptology systems, the longer it will take computers to factor the composite numbers used in the keys. Accordingly, RSA cryptology systems derive their reliability from the fact that there are an infinite number of prime numbers—and from the difficulties encountered in factoring … Web13 de dez. de 2011 · In particular, when working modulo a prime p, you are using the simplest form of finite fields: the Galois field GF(p). With a composite n, working modulo n gives less structure, Z/nZ is not a field, just a ring. However, it remains usable. Of course, when n is large and a product of two primes, working modulo n leads to RSA. incarcator huawei p40
