Answer 1

EDIT: this is a very old answer. SHA1 was deprecated in 2011 and has now been broken in practice. https://shattered.io/ Use a newer standard instead (e.g. SHA256, SHA512, etc).

If your answer to the question in my comment is "No", here's what I use:

    public static byte[] HashPassword(string password)
    {
        var provider = new SHA1CryptoServiceProvider();
        var encoding = new UnicodeEncoding();
        return provider.ComputeHash(encoding.GetBytes(password));
    }
