DropBox<\/strong> est un service quasiment incontournable pour stocker ses fichiers dans le cloud. Mais si on stocke sans probl\u00e8me les fichiers non sensibles, on a un peu de r\u00e9ticence \u00e0 envoyer ses fichiers personnels sur un h\u00e9bergement distant dont les conditions g\u00e9n\u00e9rales sont parfois obscures. CloudFogger<\/strong> vient r\u00e9pondre \u00e0 ce probl\u00e8me en permettant de chiffrer \u00e0 la vol\u00e9e les fichiers \u00e0 destination de DropBox, Box.net ou encore SkyDrive<\/strong>.<\/p>\n

\"CloudFogger\"<\/a><\/p>\n

<\/p>\n

A l\u2019heure o\u00f9 les attaques se multiplient en ligne (Sony, minist\u00e8re des finances, Diginotar, RSA, Verisign, etc.), on peut s\u2019inqui\u00e9ter \u00e0 l\u2019id\u00e9e que nos fichiers sur DropBox puisse un jour se retrouver \u00e0 d\u00e9couvert.<\/p>\n

L\u2019id\u00e9e de \u00a0CloudFogger est de chiffrer vos donn\u00e9es avant de les envoyer sur les services de stockage en ligne<\/strong>, afin de s\u00e9curiser celles-ci m\u00eame en cas de fuite chez DropBox, Box.net ou autre.<\/p>\n

Il est bien s\u00fbr possible d\u2019utiliser TrueCrypt<\/strong>, mais ce n\u2019est pas le plus efficace pour ce genre d\u2019usage. CloudFogger cr\u00e9e un disque virtuel sur votre syst\u00e8me qui chiffrera tout fichier que vous y d\u00e9poserez.<\/p>\n

Ce disque virtuel pointe vers un autre emplacement de votre disque dur o\u00f9 seront physiquement stock\u00e9s vos fichiers chiffr\u00e9s. En choisissant un dossier de DropBox comme emplacement physique des fichiers, toutes les donn\u00e9es d\u00e9pos\u00e9es dans le disque virtuel se retrouveront automatiquement chiffr\u00e9es et dans le cloud.<\/p>\n

\"cloudfogger_drive\"<\/a><\/p>\n

Si vous \u00eates utilisateur de DropBox, un sous-dossier de DropBox sera automatiquement s\u00e9lectionn\u00e9 \u00e0 l\u2019installation pour stocker les fichiers de CloudFogger.<\/p>\n

\"preferences\"<\/a><\/p>\n

Des fonctions permettent \u00e9galement de chiffrer et d\u00e9chiffrer simplement des fichiers sur le syst\u00e8me, et aussi de partager ses fichiers avec des amis.<\/p>\n

\"shellextension_sharing\"<\/a><\/p>\n

CloudFogger chiffre les donn\u00e9es en AES256<\/strong> en utilisant une cl\u00e9 unique stock\u00e9e avec chaque fichier<\/strong>. Cette cl\u00e9 est elle m\u00eame chiffr\u00e9e en RSA avec votre cl\u00e9 publique<\/strong>. Pourquoi ne pas chiffrer les donn\u00e9es directement avec votre cl\u00e9 publique ? Tout simplement pour g\u00e9rer le partage des donn\u00e9es entre utilisateurs.<\/p>\n

En effet, si plusieurs utilisateurs doivent acc\u00e9der au fichier, la cl\u00e9 AES sera stock\u00e9e autant de fois qu\u2019il y a d\u2019utilisateurs (chiffr\u00e9e avec la cl\u00e9 publique de chaque utilisateur), mais le fichier lui ne sera stock\u00e9 qu\u2019une seule fois. Chacun pourra alors d\u00e9chiffrer le fichier avec sa propre cl\u00e9 priv\u00e9e.<\/p>\n

De par sa conception, Cloufogger qui est avant tout un logiciel de chiffrement peut s\u2019adapter \u00e0 Box.net ou Skydrive mais \u00e0 bien d\u2019autres plates-formes de stockage dans le cloud.<\/p>\n
