public class RSA

extends Object

This class tests the RSA cipher implementation.

IAIK-JCE allows to use the javax.crypto.Cipher class for working with RSA ciphers. Creating a RSA cipher is done in the same way as creating a, for instance, DES or IDEA cipher by calling a proper getInstance factory method, e.g.:

Cipher rsa = Cipher.getInstance("RSA");

The supplied transformation string may be expanded to perform block formatting according to PKCS#1 with block type 1 or blocktype 2, i.e.:

 Cipher rsa = Cipher.getInstance("RSA/ECB/PKCS1Padding");
 

The further proceeding uses cipher initialization, cipher update and cipher finishing as used with any other cipher, e.g.:

 rsa.init(Cipher.ENCRYPT_MODE, public_key);
 byte[] encrypted = rsa.doFinal(plain_data);

Method Detail

start

public void start()

Performs the RSA cipher implementation test.

First a RSA key pair for 512 bit modulus is generated, which may last a few moments. Subsequently, a RSA cipher object is created for encrypting some test data. For verifying the result of the encryption process, it is decrypted again and compared with the original data.

Returns:

true if no errors occurs during en/decryption, false otherwise

main

public static void main(String[] argv)

Starts the RSA cipher implementation test.
