   For those interested here is the Case source code of a scheme for key

   Sample of the output:

   EVE: NOT (D xor D2)= 14577306244540485824
   EVE: D xor D2= 3869437829169065791

   EVE: FSCX(D2,D)= 14126811020873148126
   EVE: FSCX(D,D2) xor D= 11519582121138542071

      ...
   EVE: FSCX_REVOLVE_PRINT(D,D2,64)= 6616145336279823145

   Update: Added an encryption protocol (HAEN) and code, based on HKEX and
   the FSCX function
