Signature de la fonction new

def new(key, msg=None, digestmod=None) 

Description

new.__doc__

Create a new HMAC object.

    :Parameters:
      key : byte string
        key for the MAC object.
        It must be long enough to match the expected security level of the
        MAC. However, there is no benefit in using keys longer than the
        `digest_size` of the underlying hash algorithm.
      msg : byte string
        The very first chunk of the message to authenticate.
        It is equivalent to an early call to `HMAC.update()`.
        Optional.
    :Parameter digestmod:
        The hash to use to implement the HMAC. Default is `Crypto.Hash.MD5`.
    :Type digestmod:
        A hash module or instantiated object from `Crypto.Hash`
    :Returns: An `HMAC` object
