asp.net使用SHA1加密方式与MD5加密

添加一个textbox1控件、2个按钮
在代码最顶处引用 Imports System.Web.Security

主要代码：
Imports System.Web.Security   //必须顶部声明

// Button1为SHA1加密方式
     Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
         Dim strtext, strSHA1 As String
         strtext = TextBox1.Text
         strSHA1 = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strtext, "SHA1")
         Response.Write(strSHA1)
     End Sub
// Button2为MD5加密方式
     Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
         Dim strtext, strmd5 As String
         strtext = TextBox1.Text
         strmd5 = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strtext, "md5")
         Response.Write(strmd5)
     End Sub
