如何在wicket中提交前加密密码？

import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.form.PasswordTextField;
import org.apache.wicket.model.Model;

public class MyForm extends Form<Void> {
    private PasswordTextField passwordField;

    public MyForm(String id) {
        super(id);
        
        passwordField = new PasswordTextField("password", Model.of(""));
        add(passwordField);
    }

    @Override
    protected void onSubmit() {
        String password = passwordField.getModelObject();
        String encryptedPassword = EncryptionUtils.encrypt(password); // 使用加密工具类对密码进行加密
        
        // 提交加密后的密码到后端进行处理
        // ...
    }
}
