C Programming - RSA encryption Hi there, I'm struggling with writing a C program to encrypt and decrypt a string using the RSA algorithm (C90 language only). It can contain ONLY the following libraries: stdio, stdlib, math and string. I want to use the following function prototypes to try and implement things: /*Check whether a given number is prime or not*/ int checkPrime(int n) /*to find gcd*/ int gcd(int a, int h) void Encrypt(); void Decrypt(); int getPublicKeys(); int getPrivateKeys();...

C Programming - RSA Encryption I've tried to write a program that can encrypt and decrypt strings using RSA and want to be able to integrate it into a header file which contains codes for compression, linked list etc.. However, the use of global variables and fixed size of encryption is making it hard to do so Can someone please help me modify the following the code? I want to be able to just pass it in a string to...
