WebFeb 24, 2024 · The next thing Alice does is to arrive at the number n, which is the product of p * q. (As the product of two prime numbers, n is a semiprime.) n = p * q = 2173. Note that p and q must be kept secret. 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 e th roots of an arbitrary number, modulo N. For large RSA key …
