How can I see digital signature in assembly?

Question

I read article about "Signing an Assembly with a Strong Name";
http://resources.infosecinstitute.com/dot-net-assemblies-and-strong-name-signature/;
then I learned to get public key and public key token;
but the question :;
How can I get the digital signature from the assembly?
and how I can extract the hash from the digital signature?
I prefer to use ildasm;
thank you;

What exactly do you want to see? Do you want to check it for yourself or do you have to write code to check it? — Waescher
The article already mentions using the sn tool to verify the signature , display the token with sn -T(probably what you mean by hash) or extract the public key. Have you tried it? — Panagiotis Kanavos
to Panagiotis Kanavos, No, the hash isn't the publickeytoken; — mukhtar ghaleb

One way is to do this from C#, if you would prefer it:

// Load the certificate from your DLL file

var cert = X509Certificate.CreateFromSignedFile("path to your assembly");

// Create an instance of X509Certificate2

var cert2 = new X509Certificate2(cert);

// Use `GetCertHash()` to extract certificate's hash

var hash = cert2.GetCertHash();

Documentation about types used:
