hey, i am a cryptography specialist RSA algorithm work like that 1: choice very big primes number P,Q (1024 bits) 2: calculate N and phi, N=P*Q,phi=(P-1)*(Q-1) 3: Choose an integer e 1 < e < phi , gcd(e, phi) = 1 so now the public key is (e,phi),the public key is used for encryption 4: calculate the privet key d d ≡ e^1 mod phi(n) the privet key is (d,phi) and of course in use application p,q must choice randomly and the user can choice the e, or can generate randomly also as you see i have a master degree in cryptogrphy i am the right personne for this job greeting
