Hi,

Thanks for your early reply. Yes, I want to store my password in database.

while retriving from the database it'll come from the decrypt mode and compare with current password. if both are equals then it will goes to the next page.

but initially I want to encrypt a string and stored in database and decrypt it.


please find my code here.

import java.security.KeyPair;
import java.security.KeyPairGenerator;
import java.security.NoSuchAlgorithmException;
import java.security.PrivateKey;
import java.security.PublicKey;

import javax.crypto.Cipher;


public class EncryptionRsa {

String userName ="Hello";
String password = "hello123";
byte [] encPassword = null;
String decPassword = null;
String pass = null;
byte[] ciphertextBytes = null;
byte[] textBytes = null;

public void encryptPass(String userName, String password, PublicKey pubKey) {
try {
password = userName+password;
Cipher encCipher = Cipher.getInstance("RSA");
encCipher.init(Cipher.ENCRYPT_MODE, pubKey);
encPassword = encCipher.doFinal(password.getBytes());
System.out.println("Encrypt Password: "+encPassword);
} catch(Exception e) {
e.printStackTrace();
}
}

public void decryptPass(String userName, String password, PrivateKey priKey) {
try {
textBytes ="hari".getBytes();
Cipher decCipher = Cipher.getInstance("RSA");
decCipher.init(Cipher.ENCRYPT_MODE, priKey);
textBytes = decCipher.doFinal(pass.getBytes());
System.out.println("Decrypt Password: "+decPassword);

} catch(Exception e) {
e.printStackTrace();
}
}

public KeyPair getPrivateKey() throws NoSuchAlgorithmException {
KeyPairGenerator keygen = KeyPairGenerator.getInstance("RSA");
KeyPair keypair = keygen.generateKeyPair();
PublicKey publicKey = keypair.getPublic();
PrivateKey privatekey = keypair.getPrivate();
return new KeyPair(publicKey, privatekey);
}

public static void main(String[] args) throws Exception {
EncryptionRsa encryptionRsa = new EncryptionRsa();
KeyPair kp=encryptionRsa.getPrivateKey();
encryptionRsa.encryptPass("Hello", "hari", kp.getPublic());
encryptionRsa.decryptPass("Hello", "hari", kp.getPrivate());
}

}

Please reply ASAP.

Thanks in advance.
Hi,

currently I'm working on encryption and decryption password using RSA algorithm.

I did on some sample programs to encrypt and decrypt with RSA but not stored in DB.

How can I get correct password from DB using RSA.

Please provide me some sample code for RSA algorithm.

Hello Ranchers,

i am pleased to inform you that i passed the SCJP 5.0 (310 - 055) Today with 87%.

I know its very less score as compared to others but very short period I succeed in the exam.
i prepared for a little over 3 weeks for the exam and honestly would have been happy with anything more than 70%.
although i am not an active member of this forum, i went through many a question asked in this forum for the last
two weeks of my preparation time.
so, thanks to all of you out here who helped me a lot really.

i wanted to share my exam experience with all those who are thinking of taking this exam in the future.

To my displeasure, the centre did not provide me any pen and paper i am not sure if this has to do with any sun directive.

They centre manager was explained the exam process.

My next target certification is SCWCD exam.

I'm planning to take this exam in the month of march 2008.

have a happy and prosperous new year ahead,
regards,
Sreenivasa Rao.
