Container encryption
Container encryption is a feature provided in Disk_encryption_software which gives the user the option to use a regular file as an encrypted storage of an entire directory structure.
To access the encrypted directory structure and files, you mount it as a volume. It will then act as a regular volume within your operating system. Mounting requires authentication with a password, key files and/or other authentication methods.
The container file itself acts as a regular file within your operating system; it can be moved, copied, renamed and deleted.
Examples of software providing container encryption includes TrueCrypt and BestCrypt.
Container encryption can be distinguished from volume-level encryption and file-level encryption.
