I have a question about RSA key generation.
This is a simple RSA algorithm:
Choose p = 3 and q = 11
Compute n = p * q = 3 * 11 = 33
Compute ?(n) = (p - 1) * (q - 1) = 2 * 10 = 20
Choose e such that 1 < e < ?(n) and e and n are co-prime. Let e = 7
Compute a value for d such that (d * e) % ?(n) = 1. d=3
Public key is (e, n) => (7, 33)
Private key is (d, n) => (3, 33)
So public and private keys are numbers. but in many online encryption websites keys are like this:
How are those keys actually generated?
