内容导读
互联网集市收集整理的这篇技术教程文章主要介绍了javaGUI案例--rsaTool (rsa加解密图形化工具)，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含38020字，纯文字阅读大概需要55分钟。

本篇，我们尝试使用java开发一个图形化小工具(rsaTool)。
最终运行效果如下： 界面最上方有4个tab标签， 这4个标签页中分别实现了rsa加密、解密、签名、验签的功能。
下面我们来具体介绍下项目代码开发过程。
此项目使用的IDE是spring STS ，由于开发的是GUI程序，我们可以先安装一款可视化编辑器工具windowbuilder ，安装步骤如图：
在 help--》eclipse Marketplace --》search --》windowbuilder--》 安装 即可。
new一个java工程，起名为rsaTool。
java开发人员，无论开发什么都必须面向对象，对整个项目进行MVC划分。
img :图标资源
model： 模型层 ，java实体bean，业务bean等。
view :视图层，主要是JFrame 窗体等
由于RSA加解密需要依赖包 bcprov-jdk16-1.46.jar ，故需要在项目根目录中新建一个lib目录，将bcprov-jdk16-1.46.jar放入lib目录中并加入classpath 中。
ok，我们先来看看model 模型层 ： 有两个工具类，一个业务类。
