Constructeur Crypto.Hash.HMAC.HMAC.__init__

Signature de la constructeur __init__

def __init__(self, key, msg=None, digestmod=None) 

Description

__init__.__doc__

Create a new HMAC object.

        :Parameters:
          key : byte string
            secret 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 `update()`. Optional.
        :Parameter digestmod:
            The hash algorithm the HMAC is based on.
            Default is `Crypto.Hash.MD5`.
        :Type digestmod:
            A hash module or object instantiated from `Crypto.Hash`
