Convert SHA Hash Computation in Python in C #

Question

Can someone please help me convert the following two lines of python to C #.

hash = hmac.new(secret, data, digestmod = hashlib.sha1)
key = hash.hexdigest()[:8]

The rest looks like this if you are intersted:

#!/usr/bin/env python

import hmac
import hashlib


secret = 'mySecret'     
data = 'myData'

hash = hmac.new(secret, data, digestmod = hashlib.sha1)
key = hash.hexdigest()[:8]

print key

thank

You can use the HMACSHA1 class to calculate the hash:

class Program
{
    static void Main()
    {
        var secret = "secret";
        var data = "data";
        var hmac = new HMACSHA1(Encoding.UTF8.GetBytes(secret));
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(data));
        Console.WriteLine(BitConverter.ToString(hash));
    }
}
