Create .htpasswd files within C#

Question

For a small tool to automate website deployment I'd like to generate .htaccess and .htpasswd files. How do I create the hashes for the passwords in my code?

Answer 1

Per the documentation on the .htpasswd hashing methods here, the following should produce a suitable line of output that can be inserted into a .htpasswd file, using SHA1 as the hashing algorithm:

public static string CreateUser(string username, string password)
{
    using (var sha1 = SHA1.Create())
    {
        var hash = sha1.ComputeHash(Encoding.UTF8.GetBytes(password));
        return string.Format("{0}:{{SHA}}{1}", username, Convert.ToBase64String(hash));
    }
}

Example:

Console.WriteLine(CreateUser("TestUser", "TestPassword"));

Will output:

TestUser:{SHA}YlBiWyJt9ihwriOvjT+sB2DXFYg=

It should be straightforward to use this method to construct valid .htaccess files.
