A la suite de l\u2019atelier CRYPTOLOGIE de d\u00e9cembre 2024 anim\u00e9 par Christian Dufour reconnu pour son sens de la p\u00e9dagogie , Christian propose de continuer \u00e0 faire d\u00e9couvrir la CRYPTOLOGIE , une science tr\u00e8s ancienne par son int\u00e9r\u00eat militaire  mais pas seulement, de plus un domaine o\u00f9 la France a toujours brill\u00e9.<\/p>\n\n\n\n

    Cette science est devenue omnipr\u00e9sente dans nos activit\u00e9s quotidiennes, ne serait ce que les paiements par cartes et nos achats sur INTERNET.<\/p>\n\n\n\n

   La crypto est une discipline math\u00e9matique, mais m\u00eame si vous avez un  souvenir  \u00ab mitig\u00e9 \u00bb  de vos cours de maths au lyc\u00e9e, la connaissance  du fonctionnement des transactions  informatiques modernes  vous \u00e9vitera de faire des erreurs lourdes de cons\u00e9quences, exemple d\u2019erreur commune, diffuser sa clef priv\u00e9e \u2026.\u00e7a c’est d\u00e9ja vu. <\/p>\n\n\n\n

Les syst\u00e9mes UNIX LINUX aiment le chiffrement et ceci depuis l’origine ( 1970 ) de par la libert\u00e9 de communiquer qu’il apporte .<\/p>\n\n\n\n
