CODE PERMETTANT DE CRYPTER, DÉCRYPTER ET DE "BRUTEFORCER" AVEC L'ALGO DES ET 3DES
Information sur la source
Description
Cette page permet de crypter et de décrypter des mots de passe codés avec DES ou 3DES. Un bouton permet aussi de retrouver les mots de passe clairs en mode bruteforce (sans clé de cryptage), à condition que la longueur de clé d'origine soit petite (4 caractères maxi) vous pouvez accéder à la page en question directement à l'adresse suivante: http://82.224.14.14/divers/des.html
