MAC

In order to understand hex and type parameters read Hash

CMAC

spec

Description: Message authentication code based on block cipher.

Uses: When a block cipher is more readily available than a hash function

How to ???

import socket
import json
import os,binascii

def sending(message):
	ip = '127.0.0.1'
	port = 6613
	BUFFER_SIZE = 65536
	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	s.connect((ip, port))
	s.send(message)
	data = s.recv(BUFFER_SIZE)
        print data
	s.close()
	return data

data_js='{"version":1,"algorithm":"CMAC","type":"string","plaintext":"Hello world!",\
"hex":0,"key":"0123456789ABCDEF0123456789ABCDEF","family":"aes"}'
sending(data_js)

Calculate CMAC-AES to string "Hello world!" with the key given.

On data_js["family"] can be one of {"aes", "rc6", "mars","serpent","twofish', "cast256"}

Json to HMAC string

{"version":1,"algorithm":"CMAC","type":"string","plaintext":"your string","hex":BOOL,
"key":"Hex stringsize=32-64","family":"block flavor"}

Json to HMAC file

{"version":1,"algorithm":"CMAC","type":"file","file":"your file",
"key":"Hex stringsize=32-64","family":"block flavor"}
You can’t perform that action at this time.
