class _MACParams(tuple): (source)

View In Hierarchy

_MACParams represents the parameters necessary to compute SSH MAC (Message Authenticate Codes).

_MACParams is a tuple subclass to maintain compatibility with older versions of the code. The elements of a _MACParams are:

    0. The digest object used for the MAC
    1. The inner pad ("ipad") string
    2. The outer pad ("opad") string
    3. The size of the digest produced by the digest object

_MACParams is also an object lesson in why tuples are a bad type for public APIs.
