  Fisher information, Shannon information entropy and Statistical Complexity
are calculated for the interface of a normal metal and a superconductor, as a
function of the temperature for several materials. The order parameter
$\Psi({\bf r})$ derived from the Ginzburg-Landau theory is used as an input
together with experimental values of critical transition temperature $T_c$ and
the superconducting coherence length $\xi_0$. Analytical expressions are
obtained for information and complexity measures. Thus $T_c$ is directly
related in a simple way with disorder and complexity. An analytical relation is
found of the Fisher Information with the energy profile of superconductivity
i.e. the ratio of surface free energy and the bulk free energy. We verify that
a simple relation holds between Shannon and Fisher information i.e. a
decomposition of a global information quantity (Shannon) in terms of two local
ones (Fisher information), previously derived and verified for atoms and
molecules by Liu et al. Finally, we find analytical expressions for generalized
information measures like the Tsallis entropy and Fisher information. We
conclude that the proper value of the non-extensivity parameter $q\simeq 1$, in
agreement with previous work using a different model, where $q\simeq 1.005$.
