I have a C# string that has been built up with a stringbuilder. There are 2 lines that have the output:

Line1
Line2

I hash with this code:

public static string GetSha256Hash(string input)
{
    using (SHA256 sha256Hash = SHA256.Create())
    {
        byte[] bytes = sha256Hash.ComputeHash(Encoding.UTF8.GetBytes(input));
        return Convert.ToBase64String(bytes);
    }
}

CSPLite creates the correct following hash:

However C# creates a different hash due to the likely the line breaks that is handled differently

If I copy and paste the output of that same string, then i get the correct hash

How can I adapt the C# string in order to create the same hash as what CSP is creating?
