Programming Languages & Frameworks

Hi There,

i have a Java code for Generating Encryption Key and I would like it to be in Javascript code, please help.

package encrypt;

import org.apache.commons.codec.binary.Base64;

import javax.crypto.Cipher;

import java.io.UnsupportedEncodingException;

import java.security.NoSuchAlgorithmException;

import java.util.Arrays;

import java.security.Key;

import java.security.MessageDigest;

import javax.crypto.spec.SecretKeySpec;

public class AESEncryptor

{

    private static SecretKeySpec secretKey;

    private static byte[] key;

    private static String key1;

    public static void setKey(final String myKey, final int iterations) {

        AESEncryptor.key1 = myKey.toString();

        MessageDigest sha = null;

        try {

            AESEncryptor.key = myKey.getBytes("UTF-8");

            sha = MessageDigest.getInstance("SHA-256");

            for (int i = 1; i <= iterations; ++i) {

                AESEncryptor.key = sha.digest(AESEncryptor.key);

            }

            AESEncryptor.key = Arrays.copyOf(AESEncryptor.key, 16);

            AESEncryptor.secretKey = new SecretKeySpec(AESEncryptor.key, "AES");

        }

        catch (NoSuchAlgorithmException e) {

            e.printStackTrace();

        }

        catch (UnsupportedEncodingException e2) {

            e2.printStackTrace();

        }

    }

}
