byte[] snk = File.ReadAllBytes("YourSnkFile.snk");

use

byte[] publicKey = GetPublicKey(snk);
byte[] publicKeyToken = GetPublicKeyToken(publicKey);

with these utility methods

public static byte[] GetPublicKey(byte[] snk)
{
    var snkp = new System.Reflection.StrongNameKeyPair(snk);
    byte[] publicKey = snkp.PublicKey;
    return publicKey;
}

    {
        byte[] hash = csp.ComputeHash(publicKey);

        byte[] token = new byte[8];

        for (int i = 0; i < 8; i++)
        {
            token[i] = hash[hash.Length - i - 1];
        }
