def construct(tup) 

Description

construct.__doc__

Construct an RSA key from a tuple of valid RSA components.

        The modulus **n** must be the product of two primes.
        The public exponent **e** must be odd and larger than 1.

        In case of a private key, the following equations must apply:

        - e != 1
        - p*q = n
        - e*d = 1 mod (p-1)(q-1)
        - p*u = 1 mod q

        :Parameters:
         tup : tuple
                    A tuple of long integers, with at least 2 and no
                    more than 6 items. The items come in the following order:

                    1. RSA modulus (n).
                    2. Public exponent (e).
                    3. Private exponent (d). Only required if the key is private.
                    4. First factor of n (p). Optional.
                    5. Second factor of n (q). Optional.
                    6. CRT coefficient, (1/p) mod q (u). Optional.
        
        :Return: An RSA key object (`_RSAobj`).
