PC1 CIPHER With 128-bit keys

zaphod · Message par **zaphod** » dim. 08/févr./2009 20:21

Salut à tous,

J'ai fait un portage en pure basic du cryptage symétrique PC1.
La clé de codage est limitée à 16 caractères (128 bits).
Si ça peut servir à quelqu'un...

Merci pour ce partage

Kwai chang caine

Je ne connais pas les diverses methodes de cryptages qui ont un nom.

C'est interessant, merci pour ce partage

Bonjour à tous,

Voici ma version de cet algorithme de cryptage. Juste pour m'amuser un peu, le niveau de cryptage atteint 8192 Bits (Avec un bon mot de passe ça devrait prendre plusieurs milliards d'année pour passer à travers). J'ai également ajouté deux commandes pour générer des clés de cryptage complexes.
