MD5ofStr("message digest"));
System.out.println("MD5(\"abcdefghijklmnopqrstuvwxyz\"):"
m.getMD5ofStr("abcdefghijklmnopqrstuvwxyz"));
System.out.println("MD5(\"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789\"):"
m.getMD5ofStr("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"));
}
else
System.out.println("MD5(" args[0] ")=" m.getMD5ofStr(args[0]));

}

}

JSP中的使用方法

-------------------------------------------------------------------------------
<%@ page language='java' %>
<jsp:useBean id='oMD5' scope='request' class='beartool.MD5'/>

<%@ page import='java.util.*'%>
<%@ page import='java.sql.*'%>
<html>
<body>
<%
String userid = request.getParameter("UserID"); //获取用户输入UserID
String password = request.getParameter("Password"); //获取用户输入的Password

String pwdmd5 = oMD5.getMD5ofStr(password); //计算MD5的值

PrintWriter rp = response.getWriter();

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

Connection con = DriverManager.getConnection("jdbc:odbc:community", "", "");

Statement stmt = con.createStatement();

ResultSet rs = stmt.executeQuery("select * from users where userID ='" userid "' and pwdmd5= '" pwdmd5 "'" );

if (rs.next())
{
rp.print("Login OK");

}
else
{
rp.print("Login Fail");
}

stmt.close();
con.close();

%>

</body>
