ASP.Net中的MD5加密
类别: ASP教程 
其实在ASP.Net编程中，不用调用md5.asp来加密数据。在DotNet中有自带的类：System.Web.Security.HashPasswordForStoringInConfigFile()
public string md5(string str,int code)
{
if(code==16) //16位MD5加密（取32位加密的9~25字符）
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower().Substring(8,16) ;
}
if(code==32) //32位加密
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower();
}
return "00000000000000000000000000000000";
}
public string md5(string str,int code)
{
if(code==16) //16位MD5加密（取32位加密的9~25字符）
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower().Substring(8,16) ;
}
if(code==32) //32位加密
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str,"MD5").ToLower();
}
return "00000000000000000000000000000000";
}
