Is there a simple way to intersect two strings? I did not find anything about that.

intersect["abcdEfgh","blahcdEzz"] (* "cdE" *)

By intersection, I mean the longest substring(s) that is(are) common to both strings.

As porposed by @V.E. you should use LongestCommonSubsequence[s1,s2]. Example from the documentation:

LongestCommonSubsequence[ "AAABBBBCCCCC", "CCCBBBAAABABA"]
(* AAAB *)
