Suppose that Bob's private exponent is learned by other users. Rather than generating a new modulus, Bob decides to generate just a new public and a new private exponent e ′ and d ′. Is this safe for Bob? rsa public-key symmetric with respect to the origin examples https://acquisition-labs.com

N is the product of randomly chosen prime numbers, p and q. The decryption exponent, d, is the private key: d=e−1 mod (p−1) (q−1) = e−1 mod φ (N) φ (N) denotes Euler's totient function. That is, given an integer 'k' such that ed − kφ (N)=1, so: φ (N) = (ed − 1) / k thaby
