hi.
i started to write an addon for Mega.nz ,
i almost got it, i was able to get the download link the problem is that the data is encrypted i dont know how to play this, i am adding my code (basicly its not my code i found it on Github and modified it).
how can i send the decryptor to "xbmcplugin.setResolvedUrl"?
 thanks for all your help.

python:


def getfile(file_id, file_key):



    key = base64_to_a32(file_key)



    k = (key[0] ^ key[4], key[1] ^ key[5], key[2] ^ key[6], key[3] ^ key[7])

    iv = key[4:6] + (0, 0)

    meta_mac = key[6:8]



    file = api_req({'a': 'g', 'g': 1, 'p': file_id})

    dl_url = file['g']

    size = file['s']



    attributes = base64urldecode(file['at'])

    attributes = dec_attr(attributes, k)



    logging.warning( "Downloading %s (size: %d), url = %s" % (attributes['n'], size, dl_url))

    

    infile = urllib.urlopen(dl_url)

    loc=os.path.join(user_dataDir,'down.mkv')

    outfile = open(loc, 'wb')



#here is the decryptor !!!



    decryptor = AES.new(a32_to_str(k), AES.MODE_CTR, counter=Counter.new(128, initial_value=((iv[0] << 32) + iv[1]) << 64))

    return dl_url

    file_mac = [0, 0, 0, 0]

    x=0

    for chunk_start, chunk_size in sorted(get_chunks(file['s']).items()):

        chunk = infile.read(chunk_size)

        chunk = decryptor.decrypt(chunk)

        outfile.write(chunk)

        

        chunk_mac = [iv[0], iv[1], iv[0], iv[1]]

        for i in xrange(0, len(chunk), 16):

            block = chunk[i:i+16]

            if len(block) % 16:

                block += '\0' * (16 - (len(block) % 16))

            block = str_to_a32(block)

            chunk_mac = [chunk_mac[0] ^ block[0], chunk_mac[1] ^ block[1], chunk_mac[2] ^ block[2], chunk_mac[3] ^ block[3]]

            chunk_mac = aes_cbc_encrypt_a32(chunk_mac, k)

            

        file_mac = [file_mac[0] ^ chunk_mac[0], file_mac[1] ^ chunk_mac[1], file_mac[2] ^ chunk_mac[2], file_mac[3] ^ chunk_mac[3]]

        file_mac = aes_cbc_encrypt_a32(file_mac, k)

        

    outfile.close()

    infile.close()



    if (file_mac[0] ^ file_mac[1], file_mac[2] ^ file_mac[3]) != meta_mac:

        print "MAC mismatch"

    else:

        print "MAC OK"
