Cryptage
A text encryption tool, based on AES cryptography
How it works:
Mark needs to send personal text to Sarah, and wants that only Sarah can read it.
Mark writes here in Input field the text.
A password is automatically created. Or Mark and Sarah can estabilish a password for every communications over a secure channel (by voice, for example).
Mark can send the encrypted field OR the sharing url field over an insecure channel (for example a chat, mail, Skype, Facebook etc) where Sarah can read it.
Sarah opens the sharing url (or opens this page and pastes the encrypted text), enters the password and can read the original message in the decrypted field.
Note:MyWhisper.net and NOBODY in the network can technically see neither the original text nor the password, and not even the encrypted text if sharing url version isn't used, because all stuffs are only in Mark and Sarah browsers and all encryption/decryption is performed by their browsers with javascript. Therefore HTTPS/SSL access is useless.

DeepSound is a steganography tool that hides secret data into audio files - wave and flac. The application also enables you to extract secret files directly from wav, flac, wma lossless or audio CD tracks. DeepSound might be used as copyright marking software for wave, flac, wma and audio CD. DeepSound also support encrypting secret files using AES-256(Advanced Encryption Standard) to improve data protection.
Cryptocat is free software that aims to provide an open, accessible Instant Messaging environment that encrypts your conversations and works right in your browser.
Cryptocat is an open source experiment — the goal is to provide the easiest, most accessible way to chat while maintaining your privacy online, because we believe in Internet privacy.

Dans l’épisode précédent "La sécurisation des mots de passe, c’est salée", j’avais expliqué l’intérêt du sel pour protéger les mots de passe de ses utilisateurs. On va voir désormais que cela n’est toujours pas suffisant, et que seul les poissons volants (blowfish) pourront nous sauver la mise !
Saler et hacher ne suffit pas
A la lecture de deux très bons articles sur le sujet : How to safely store a password (en), Exemple de stockage de mot de passe en Java : hashage et salage, est-ce suffisant ? ; on se rend compte que saler et hacher ne suffit pas !

BoxCryptor est un utilitaire permettant de crypter des données de manière entièrement sécurisée (il utilise l'algorithme de cryptage AES 256 bits). Il crée un dossier où seront stockés vos fichiers cryptés sur votre ordinateur à l'emplacement de votre choix (par exemple votre Dropbox) et qui sera accessible par l'intermédiaire d'un lecteur de disque virtuel. Toutes les données déposées dans le lecteur virtuel sont automatiquement cryptées à la volée, il est donc très aisé de l'utiliser avec un service cloud en ligne de type Dropbox ou Google Drive pour synchroniser vos fichiers sensibles et les conserver dans le nuage sans se soucier pour la confidentialité de ceux-ci.
