HashPasswordForStoringInConfigFile方法使用起來很簡單，它支持"SHA1"和"MD5"加密算法。
下面的代碼簡單的演示了關于其用法：
復制代碼 代碼如下:
<%@ Page language="c#" %>
<%@ Import Namespace="System.Web.Security" %>
<html>
<head>
<script language="C#" runat="server">
public void encryptString(Object sender, EventArgs e)
{
SHA1.Text = FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text,"SHA1");
MD5.Text =FormsAuthentication.HashPasswordForStoringInConfigFile(txtPassword.Text, "MD5") ;
}
</script>
</head>
<body>
<form runat="server" ID="Form1">
<p>
<b>Original Clear Text Password: </b>
<br/>
<ASP:Textbox id="txtPassword" runat="server" />
<ASP:Button runat="server" text="Encrypt String" onClick="encryptString" ID="Button1" />
</p>
<p>
<b>Encrypted Password In SHA1: </b>
<ASP:label id="SHA1" runat="server" />
</p>
<p>
<b>Encrypted Password In MD5: </b>
<ASP:label id="MD5" runat="server" />
</p>
</form>
</body>
</html>
正如你所看到的這樣簡單易用。我們可以把這段加密程序封裝在一個函數里便于重復的使用。代碼如下：
復制代碼 代碼如下:
public string EncryptPassword(string PasswordString,string PasswordFormat )
{
if (PasswordFormat="SHA1")
{
EncryptPassword=FormsAuthortication.HashPasswordForStoringInConfigFile(PasswordString ,"SHA1");
}
elseif (PasswordFormat="MD5")
{
EncryptPassword=FormsAuthortication.HashPasswordForStoringInConfigFile(PasswordString ,"MD5");
}
else
{
EncryptPassword="";
}
}
MD5的一些應用
復制代碼 代碼如下:
string payKey = getPayKey(WebDataParse.TryIntParse(partner, 0));
string signMsgVal = partner + out_orderId + userId + serverId + total_fee + notify_url + payKey;
signMsgVal = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(signMsgVal, "md5").ToUpper();
if (signMsgVal == signMsg)
return true;
