Solve the following python programming problem given the following code:
def _make_secret_payload(self, encoded_secret) : 
    'Builds payload out of binary secret.

    Args:
      encoded_secret: Binary form of secret (any type).

    Returns:
      Binary value to be used as the secret payload.
    ' 
    servercert = M2Crypto.X509.load_cert_der_string (self.ssl.getpeercert (True)) 
    clientcert = M2Crypto.X509.load_cert (self.certfile) 
    def get_key_pair(c) : 
        return [remove_null_bytes (v [4 :]) for v in c.get_pubkey ().get_rsa ().pub ()] 
def remove_null_bytes(v) : 
        return ''.join (itertools.dropwhile ((lambda x : (x == '\x00')), v)) 
(sexp, smod) = get_key_pair (servercert) 
    (cexp, cmod) = get_key_pair (get_key_pair) 
    digest = hashlib.sha256 () 
    digest.update (cmod) 
    digest.update (cexp) 
    digest.update (smod) 
    digest.update (sexp) 
    digest.update (encoded_secret [(len (encoded_secret) // 2) :]) 
    return digest.digest () 

    
    

    Fix the buggy line: (cexp, cmod) = get_key_pair (get_key_pair)
assistant
#Here is Python program to fix the buggy line: (cexp, cmod) = get_key_pair (get_key_pair)
.

(cexp, cmod) = get_key_pair (clientcert)
