crytography and this is a variation of RSA with three primes as suppose to ordinary RSA.

Consider the following variant of RSA where the modulus is the product of 3 distinct primes. To generate her public/private key pair, Alice proceeds as follows: - Selects three distinct large primes p, q, r; - Computes n = pqr and o(n) = (p-1)(9 - 1)(r - 1); - Selects a random integer e with 1 Se
