  A fermionic disordered one dimensional wire in the presence of attractive
interactions is known to have two distinct phases: A localized and a
superconducting one depending on the strength of interaction and disorder. The
localized region may also exhibit a metallic behaviour if the system size is
shorter than the localization length. Here we show that the superconducting
phase has a distinct distribution of the entanglement entropy and entanglement
spectrum distinct from the metallic regime. The entanglement entropy
distribution is strongly asymmetric with L\'evy alpha stable distribution
(compared to the Gaussian metallic distribution), and the entanglement level
spacing distribution is unitary (compared to orthogonal). Thus, entanglement
properties may reveal properties which can not be detected by other methods.
