VMAC

MAC

In order to understand hex and type parameters read Hash

VMAC

spec

Description: Message authentication code based on universal hash.

Uses: High performance on 64-bit machines

How to ???

import requests
import json
import os,binascii

def sending(message):
    url = 'http://127.0.0.1:6613/'
    response = requests.post(url, data=message)
    print response.content
    return response.content

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

Calculate VMAC-AES to string "Hello world!" with the key and iv given.

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

Json to HMAC string

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

Json to HMAC file

{"version":1,"algorithm":"CMAC","type":"file","file":"your file",
"key":"Hex stringsize=32-64","iv":"Hex stringsize=32","family":"block flavor"}
