WebRSA uses the Euler φ function of n to calculate the secret key. This is defined as. φ ( n) = ( p − 1) × ( q − 1) = 120. The prerequisit here is that p and q are different. Otherwise, the φ function would be calculated differently. It is important for RSA that the value of the φ function is coprime to e (the largest common divisor must ...
