KriptaRSA-Java

An implementation of Asymmetric encryption of kriptaRSA in Java.

Requirements

• There are some externals lib to import to the project, availables on ./KriptaRSA/lib/

How to use

HOW TO CODE

This is how it's work in the code:

package kripta;
public class Example {

    public static void main(String args[]) throws Exception {

        // Instantiate the KriptaRSA
        KriptaRSA k = new KriptaRSA();

        // You can generate KeyPairs here:
        // System.out.println(k.generate_RSA())

        // You can set/get PublicKey or Private key :
        k.setPublicKey("-----BEGIN PUBLIC KEY-----\n"+

OUTPUT

This is what your code will return:
