def construct(tup) 

Description

construct.__doc__

Construct a DSA key from a tuple of valid DSA components.

        The modulus *p* must be a prime.

        The following equations must apply:

        - p-1 = 0 mod q
        - g^x = y mod p
        - 0 < x < q
        - 1 < g < p

        :Parameters:
         tup : tuple
                    A tuple of long integers, with 4 or 5 items
                    in the following order:

                    1. Public key (*y*).
                    2. Sub-group generator (*g*).
                    3. Modulus, finite field order (*p*).
                    4. Sub-group order (*q*).
                    5. Private key (*x*). Optional.

        :Return: A DSA key object (`_DSAobj`).
