[Cryptix-users] java.lang.ClassCastException

[Faveh K. <kav...@ya...>]

Hi,
 
I am using Cryptix 3 and I get the followoing error:
 
java.lang.ClassCastException:
com.sun.rsajca.JSA_RSAPublicKey

when I run the following code:
 
  public void computeKeys(int size) {
        try {
            KeyPairGenerator kpg =
KeyPairGenerator.getInstance("RSA");
            Cipher cipher = Cipher.getInstance("RSA");
            
            kpg.initialize(size, prng);
            System.out.print(". ");
            KeyPair pair = kpg.generateKeyPair();
            System.out.print(". ");
            PrivateKey sk = pair.getPrivate();
            System.out.print(". ");
            PublicKey pk = pair.getPublic();
            System.out.println(". Done!\n");
            
            System.out.println("Getting simple key
components...");
            
            BigInteger m = ((CryptixRSAPublicKey)
pk).getModulus();
            BigInteger e = ((CryptixRSAPublicKey)
pk).getExponent();
            System.out.println("   Public key
material:");
            System.out.println("   n: " +
BI.dumpString(m));
            System.out.println("   e: " +
BI.dumpString(e));
 
            BigInteger n = ((CryptixRSAPrivateKey)
sk).getModulus();
            BigInteger d = ((CryptixRSAPrivateKey)
sk).getExponent();
            BigInteger p = ((RSAFactors) sk).getP();
            BigInteger q = ((RSAFactors) sk).getQ();
            BigInteger u = ((RSAFactors)
sk).getInverseOfQModP();
            System.out.println("   Private key
material:");
            System.out.println("   n: " +
BI.dumpString(n));
            System.out.println("   d: " +
BI.dumpString(d));
            System.out.println("   p: " +
BI.dumpString(p));
            System.out.println("   q: " +
BI.dumpString(q));
            System.out.println("   u: " +
BI.dumpString(u));
            
            
        } catch (Exception e) {
            System.out.println(e);
        }
        return;
    }
 
Your help will be very much appreciated. Thanks in
advance.
