Thread: Encryption password by java MD5 and UTF-8

Hello, I wanna help from any one. I need java encryption password what will be make by MD5 and UTF-8. I wrote some code when i run this program here show some error. Please check and give me full instruction because i m totally new on java programming.

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import sun.misc.BASE64Encoder;
 
public final class MyPasswordEncrypt {
    public static synchronized String encrypt(String plaintext,
            String algorithm, String encoding) throws Exception {
        MessageDigest msgDigest = null;
        String hashValue = null;
        try {
            msgDigest = MessageDigest.getInstance(algorithm);
            msgDigest.update(plaintext.getBytes(encoding));
            byte rawByte[] = msgDigest.digest();
            hashValue = (new BASE64Encoder()).encode(rawByte);
 
        } catch (NoSuchAlgorithmException e) {
            System.out.println("No Such Algorithm Exists");
        } catch (UnsupportedEncodingException e) {
            System.out.println("The Encoding Is Not Supported");
        }
        return hashValue;
    }
 
    public static void main(String args[]) throws Exception {
        String plainPassword = "SecretPassword";
 
        System.out.println("PlainText\tAlgo\tEncoding\tEncrypted Password");
        System.out.println(plainPassword + "\tSHA\tUTF-8\t"
                + encrypt("MySecretPassword", "SHA", "UTF-8"));
        System.out.println(plainPassword + "\tSHA-1\tUTF-16\t"
                + encrypt("MySecretPassword", "SHA-1", "UTF-16"));
        System.out.println(plainPassword + "\tMD5\tUTF-8\t"
                + encrypt("MySecretPassword", "MD5", "UTF-8"));
        System.out.println(plainPassword + "\tMD5\tUTF-16\t"
                + encrypt("MySecretPassword", "MD5", "UTF-16"));
 
    }
}

show some error.

Please post the full text of the error message.

Also please Edit your post and wrap your code with
[code=java]
<YOUR CODE HERE>
[/code]
to get highlighting and preserve formatting.

Please explain what your problem is. Post your code and ask any questions you may have about it.

If you want to remove the warning, find another class to use.

Try google.

how can i solve java warning?

Find another class to do the Base64 encoding.

Try using a search for base64 to find out about it.

Perhaps you can find a free class that will do Base64 coding.
