Cryptainer is a simple, easy to use encryption software that creates an encrypted virtual drive, provides password protection and hides any file or folder ensuring file encryption, automatically. Its powerful encryption ensures that only you can access your data.  
The free, fully-functional Cryptainer LE version uses a 128-bit implementation of the powerful Blowfish algorithm while the registered versions Cryptainer ME, Cryptainer PE and Cryptainer 9.0 offer a choice between a 448-bit implementation of Blowfish and a 256-bit implementation of AES (Rijndael).  
Cryptainer creates a volume (vault) that can only be accessed with a password. This volume stores files in the encrypted form. Once mounted, the Cryptainer drive is like any other drive you normally work with. It functions like any other drive (C: or D:) on your computer. Just drag and drop any file into the Cryptainer Vault. It is automatically encrypted. It's that simple! Cryptainer vaults can only be viewed, accessed, browsed or modified by the user who has the key to open it. At other times, the files are invisible!  
The Cryptainer Drive is actually a file. All data is stored encrypted within this drive. When mounted using the Cryptainer interface with your password, it appears to Windows as a Disk. Consequently, unless it is actually loaded using Cryptainer, it is not visible under Windows or DOS for that matter. There are no files or any information visible.  
All information is stored in the form of encrypted files in a special 'volume' that disappears when you password protect it, thereby locking your files and folders. Any kind of file can be dragged and dropped into this volume, rendering it totally inaccessible by anyone but you. Thus, even if your "vault" (volume file) is stolen or downloaded by anyone, it is not possible to read your data. Using encryption in Cryptainer, it would take more than the age of the universe for all the computers in the world working simultaneously to decipher an encrypted file.  
These volumes can be transported (moved/copied) to any location (another folder, another drive or even to a CD). Cryptainer combines ease of use with state-of-the-art technology to ensure total security, zero learning curve and maximum convenience! Cryptainer offers true on-the-fly disk encryption making sure that absolutely anyone can use it effectively! What you get is foolproof, hassle-free, unbreakable computer security.  
Cryptainer runs on all versions of MS Windows (Windows 95, Windows 98, Windows ME, Windows 2000, Windows 2003 Server, Windows XP 32-bit/64-bit, Windows Vista 32-bit/64bit, Windows 7 32-bit/64bit, Windows 8 32-bit/64-bit) as a special Windows device driver operating on an implementation of the Blowfish algorithm in Cipher Block Chaining (CBC) mode with a block size of 64 bits and conforms to international standards.
