 RSA big numbers computation -> raise to power, how?. AWriter28-Sep-09 3:37 AWriter 28-Sep-09 3:37
 Hello to all! I want to implement in C# the RSA algorithm to encrypt and decrypt some data. I've studiet a lot already about this algorithm, but the only thing that I don't understand how to work with very big numbers in C#, even in C++ or C. The problem is, that in our days, the recommended minimal lenght of the RSA key is 1024 bits. So, the algorithm says: * n = pq, where p and q are distinct primes. * phi, φ = (p-1)(q-1) * e < n such that gcd(e, phi)=1 * d = e-1 mod phi. * c = me mod n, 1How to raise a message, lets say the encrypted '10' to our d, that is 6208033627, to obtain the original message? And after all, our d is only 33 bits length? Tha maximal System.Double value is some 10 at the 308 power. What I don't understand? What I'm missing? Can anyone explain me this? I will apreciate your explanation! Thank you in advance!
