Web2. The private key d of RSA algorithm with public parameters ( N, e) is such that: e d ≡ 1 mod ϕ ( N). Since by definition e and ϕ ( N) are coprime then with extended euclidean algorithm you can find such d: e d + k ϕ ( N) = 1. Consider that to compute ϕ ( N) you should know how to factor N since ϕ ( N) = ϕ ( p) ϕ ( q) = ( p − 1) ( q ...
