You have two types of hashes you can do, MD5 or SHA1. The following method gives you a SHA1 hash string of the string it receives.

public string CreateSHA1PasswordHash(string inputString)
{
	SHA1 sha1 = new SHA1CryptoServiceProvider();  
	byte[] buffer = Encoding.UTF8.GetBytes(inputString); 
	byte[] cipher = sha1.ComputeHash(buffer);
	StringBuilder sb = new StringBuilder(cipher.Length * 2);  
	for (int i=0; i<cipher.Length; i++)  
           sb.Append(cipher[i].ToString("x2"));  
	return sb.ToString();
}

Hope this helps.

Typically, you'd use the Cryptography namespace, pick an algorithm, salt your password and pass a hash into SQL Server. Then you'd pass the user input, also salted and hashed, to a stored proc that returns if the username/password combination is valid

Hello...

Are there any possibilities to get all available domains in network ?
(Just like the login windows. The user can choose domain from DropDownList)

Thanks...

Installing a windows service on a windows 2003 server

Hi,

I have a problem installing my windows service on a windows 2003 Server, user is a administrator.
I have no problem installing the same service under Windows XP.

I get the following error message:

An exception occurred while trying to find the installers in the c:\program files\archivetool\archivetool.exe assembly.
System.Reflection.ReflectionTypeLoadException: One or more of the types in the assembly unable to load.
Aborting installation for c:\program files\archivetool\archivetool.exe.
Rolling back assembly 'c:\program files\archivetool\archivetool.exe'.
Affected parameters are:
assemblypath = c:\program files\archivetool\archivetool.exe
logfile = c:\program files\archivetool\archivetool.InstallLog

Searching internet forum I get the idea that something with the .net Framework 1.1 ( which is the framework I need to run my service) is wrong. But I checked that the newest version of the .net Framework 1.1 for windows 2003 server is installed.

Does any of you have an idea? Iam really stuck.

thanks.

Hi, check out this page: http://blogs.msdn.com/suzcook/archive/2003/08/11/57236.aspx[^]. It shows how to get more information about the exception and hopefully you will find out why this exception is being thrown.
