StealthDisk Mobile использует технологию виртуального диска для простого и секретного сохранения всех важных файлов и документов. Программа создает зашифрованный виртуальный диск, на котором во время работы налету шифруются и дешифруются все данные. Когда работа закончена, надо просто демонтировать раздел StealthDisk и все важные файлы и документы останутся в невидимом и зашифрованном виде. По 1-ой ссылке русская версия, по 2-ой английская.
Программа позволяет шифровать USB-диски, Firewire-диски, жесткие диски, съемные диски, pen- и thumb-диски, CDR и другие портативные устройства хранения информации. StealthDisk Mobile запускается прямо с устройства хранения данных и не требует инсталляции

StealthDisk Mobile uses Virtual Disk Technology to easily and securely store all your important files and documents. Using industry-leading encryption algorithms, StealthDisk Mobile creates an encrypted virtual disk that encrypts and decrypts all data on-the-fly as you work. When you are done, simply dismount the StealthDisk volume and all your important files and documents will be instantly hidden and encrypted. There is no need to encrypt each and every file or each and every every folder like other file encryption applications.

Key Benefits:
Speed
All our algorithms are optimized and blazing fast! Our software processes data on-the-fly meaning data only gets decrypted when it is accessed. Other file encryption software encrypts or decrypts the entire file before you can use it. StealthDisk Mobile does this automatically and only to the data that you access saving valuable time and resources.

Security
We use only industry trusted and proven algorithms. We don't have a long list of algorithms because we carefully select only the best and most secure. Among the chosen algorithms is AES, the Advanced Encryption Standard, selected by the NIST to be the US Federal Government standard to protect sensitive information.

Easy and Convenient
By using Virtual Disk Technology, we've made security as simple as using your hard disk. Files can be created, saved and opened just as before. As long as they are put onto the StealthDisk volume, they are automatically encrypted or decrypted on-the-fly. Furthermore, you can burn StealthDisk volumes onto optical media such as CD-R and take them with you, wherever you go.

Features:
No installation required.
Hides all Images, Videos and Documents.
Easy to use, just like using your regular Hard Disk.
On-The-Fly Encryption for Instant File Hiding.
Supports AES with 128-bit and 256-bit key lengths.
Supports Blowfish with 128-bit and 448-bit key lengths.
Further increase your security by using an External Header Block (encrypted) to separate key information and ciphertext.
Unlimited volume size. No 20MB or similar limits like other products. You can create volumes as large as your Operating System allows.
No mount limits. Mount as many volumes as you have available drive letters. Other products have limits of 1 or maybe 4 concurrently mounted volumes.
Supports mounting volumes over a Local Area Network.
Supports mounting volumes as Read Only.
Supports Auto Dismounting of idle drives.

System Requirements:
Pentium III or higher
Windows 2000/XP/2003
128MB of RAM
2MB of available hard-disk space
