Beginner: MD5 under the. NET Framework

The. NET Framework has recently found programmers in. NET project in order to avoid unnecessary resource consumption, write the MD5 algorithm to achieve this article.

. NET Framework, the MD5 implementation has been integrated into the System.Web.Security namespace with a simple call to get the result:
String result strings =system.web.security.formsauthentication.hashpasswordforstoringinconfigfile (input string, "MD5");



The following wrapper functions return the 16-bit and 32-bit MD5 cryptographic strings of the parameter str, depending on the different code parameters (preferably 16 or 32).
(16-bit string used to simulate the dynamic Network forum and other domestic common forum MD5 Implementation)



public string MD5 (string Str,int code)
{

if (code==16)
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile (str, "MD5"). ToLower (). Substring (8,16);
}

if (code==32)
{
return System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile (str, "MD5");
}

return "00000000000000000000000000000000";
}


System.Web.Security the other methods of namespace encapsulation, see MSDN.
