Modify SERVU Database Password Servu encryption method

The project requires users to modify the Servu password themselves. SERVU can access the Access\mysql\sqlserver database through ODBC. We can modify it directly by creating the Web.

But the problem is, the password is encrypted ... Find out how to encrypt the. NET version by searching online ... Self-verification No problem ...

The following is a simple test code (quote others blog)

Strpasswordfronttwochars = strpassword.substring (0, 2);
if (Createcrypassword (Strpasswordfronttwochars, "gzf") = = strpassword)

Generates an encrypted password from the specified random letter and login password
public string Createcrypassword (string strfrontchars, String strpassword)
{
return strfrontchars + MD5 (strfrontchars + strpassword). ToUpper (). Trim ();
}

Determine if the password input is the same two times
if (txtnewpassword.text! = txtconfirmpassword.text)
//{
controlmessage.innerhtml = "Two times the password entered is inconsistent, please re-enter";
Return
//}

IniFile ini = new IniFile (_strservudaemonpath);
String strsectionvalue = "user=" + struserid.trim () + "1";

Determines whether the user exists by reading the homedir of the specified user
if (INI. ReadString (Strsectionvalue, "Homedir", "") = = = "")
//{
controlmessage.innerhtml = "The specified user does not exist";
Return
//}

Start judging if the password is correct
String strpassword = ini. ReadString (Strsectionvalue, "Password", "" ");

}
