Problem 44956. Determine RSA keys (public and private) given two prime number character strings (p and q)
Given two prime number character strings (p and q), generate the RSA public and private keys (n and d) with e = 65537. The more difficult part is doing this without the use of symbolic numbers. Example: p = '3355335697481001330501721', q = '5955344080483688912855719' n='19982178584029090861856118769095354822153154192399' d='3270348772331599380262578849367006078599068947553'

I think my main issue is that I cannot use the mod function with large numbers, what is a way around this?

@David Hill. Thanks, that worked a lot better for me

One should first consider if MATLAB is even adapted for these kinds of calculations. Still, I had a lot of fun.
