So I'm trying to write this program in C that will take a message the user types in and encrypt it using an RSA public key that the user supplies. I know there are encryption functions and libraries in C but I want to actually recreate the algorithm in code …

I am implementing RSA in C++ and here's my design(code structure). *keygen.h* namespace rsa{ class keygen{ public: //Constructor keygen(size); //Generate keys void generate(); //Getters string gete(){ return xyz; } .. .. .. private: //initializes bignums void initall(); keygen(){} //Private Member variables goes here } } *prime.h* namespace rsa{ //First 100 …

I have been programming in C++ for a while now. I heard about RSA Encryption algorithm, and i have read many online sites on how it works. But i still cant grasp how the algorithm works. i have tried to make programs with RSA, but they doesnt encrypt. If you …

I am working for encryption and decryption using rsa algorithm ,and adding my own concept in rsa, after rsa and padding i m getting a string like- 100011234A12300A12A231A234A981A for different input output string is increase... Is there any technique by use of that i can compact this string [ then …

Hi, I need to find p,q and e values for RSA. Here is a simple & short description of RSA. [QUOTE]Your enter a word (actually it is a sentence but for now a word) then program will convert letters to numbers (like a=1 m=13 etc.) and group them. Use with …

How would one calculate the number of bytes of plaintext that could be encrypted as a single block given the key size? And how could you then calculate the number of bytes of cipher text that can be decrypted in a single block given the same key size because I …
