WebMethod 1: Prime numbers factorization of n n to find p p and q q. The RSA cipher is based on the assumption that it is not possible to quickly find the values p p and q q, which is why the value n n is public. To find the private key, a hacker must be able to perform the prime factorization of the number n n to find its 2 factors p p and q q.

WebStep 1: In the first step, select two large prime numbers, p and q. p = 3 q = 13 Step 2: Multiply these numbers to find n = p x q, where n is called the modulus for encryption and decryption. First, we calculate n = p x q n = 3 x 13 n = 39 Step 3: If n = p x q, then the public key is .
