M2Crypto.EVP.HMAC presents the same interface, only difference being
that its __init__() accepts an additional parameter 'key':

>>> from M2Crypto.EVP import HMAC
>>> h1 = HMAC(key='key', 'sha1')
>>> h1.update('abc')
>>> h1.digest()
"O\320\262\025'n\361/+>L\216\312\302\201\024\230\266V\374"


M2Crypto.EVP.hmac() is a convenience function:

>>> from M2Crypto.EVP import hmac
>>> hmac('key', 'abc', 'sha1')
"O\320\262\025'n\361/+>L\216\312\302\201\024\230\266V\374"
