WebIn cryptography, the RSA problem summarizes the task of performing an RSA private-key operation given only the public key. The RSA algorithm raises a message to an exponent, modulo a composite number N whose factors are not known. Thus, the task can be neatly described as finding the eth roots of an arbitrary number, modulo N. WebThis is also called public key cryptography, because one of the keys can be given to anyone. The other key must be kept private. The other key must be kept private. The algorithm is based on the fact that finding the factors of a large composite number is difficult: when the factors are prime numbers , the problem is called prime factorization .

WebHere's what is going on: d = (k * phi (n) + 1)/e which is really just d * e = k * phi (n) +1 which is really just d * e mod phi (n) = 1 The value of k doesn't really matter (if we are clever we can calculate d without knowing k). What does matter is that: -some k exists -d is the modular inverse of e ( mod phi (n) )
