utilise la m=E9thode suivante pour la construction du masque
Hash1=3DSHA-512(cl=E9 + vecteur d'initialisation)
Hash2=3DSHA-512(Hash1+cl=E9)
Hash3=3DSHA-512(Hash2+cl=E9)
et ainsi de suite !=20
on lit ensuite les chaines hexad=E9cimale par s=E9rie de deux caract=E8res =
, le premier correspondant =E0 la rang=E9e et le deuxi=E8me =E0 la colonne =
d'une table ASCII pour obtenir le masque d=E9finitif.
Pass=E9 ensuite dans ENT.exe on obtient des r=E9sultats qui semblent vraime=
nt tr=E8s proche de l'al=E9atoire.
