import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

import java.io.IOException;

public class Base64Util {

    public static byte[] decryptBASE64(String key) throws IOException {
        return new BASE64Decoder().decodeBuffer(key);
    }
    public static String encryptBASE64(byte[] key){
        return new BASE64Encoder().encodeBuffer(key);
    }
}
