很简单的，请帮我解释一下

[chinawaff]

帮我解释一下这几行程序，谢了。

public class Encrypt
{

java.security.Key key;

public Encrypt()
{
key = new Object() /* anonymous class not found */
class com.metasoft.framework.pub.util._anm1 {}

;
}

public java.lang.String enCode(java.lang.String s)
{
return (new DES()).stringEnc(s, "metacrm");
}

public java.lang.String deCode(java.lang.String s)
{
return (new DES()).stringDec(s, "metacrm");
}

public static void main(java.lang.String args[])
throws java.lang.Exception
{
com.metasoft.framework.pub.util.Encrypt pe = new Encrypt();
java.lang.String enS = pe.enCode("wjr");
java.lang.String deS = pe.deCode(enS);
java.lang.System.out.println(enS);
java.lang.System.out.println(deS);
}
}

实际上我是想看懂这个意思

po.updateLoginuserPW(loginID, (new Encrypt()).enCode(strNew));

应该是把密码加密了，可以我看不懂 后面 (new Encrypt()).enCode(strNew) 的 意思，估计是利用上的方式加密的，但具体如何加密的我就不知道，能告诉我吗？

万分感谢，在线等

[chinawaff]

那它具体的加密方式是什么呢？

能说清楚点吗？

[chinawaff]

哦，那我找找 DES 类吧

[chinawaff]

我给出这个详细代码

你能告诉我，大概在哪个文件里找吗？谢谢

学习中。。。顶起

(new Encrypt()).enCode(strNew)

是 调用 Encrypt 类中的 enCode 方法

public java.lang.String enCode(java.lang.String s)
{
return (new DES()).stringEnc(s, "metacrm");
}

这里返回 des 类中的 stringEnc 方法加密字符串 ， s 就是 你传递进来的 strNew
