近初步接触了下Java加密和数字签名的相关内容，我学习的过程大概分五步：
1）消息摘要
2）私钥加密
3）公钥加密
4）数字签名
5) 数字证书
下面的代码是第二部分：私钥加密
希望能为刚刚接触这个的朋友们省点事

用命令 whereis java就可以看到了
eg:
-bash-3.1$ whereis java
java: /usr/bin/java /etc/java /usr/lib/java /usr/share/java /opt/jdk1.6.0_01/bin/java
如果仅仅想知道java执行路径在那里的话 用which java就可以了
eg:
-bash-3.1$ which java
/usr/bin/java ......
