Virtualization of file system encryption

A computer program product comprising:

• a computer usable medium including computer usable program code for using a virtual file system to encrypt files, said computer program product comprising:
• computer usable program code for registering a plurality of file systems on a data processing system with the virtual file system, wherein the virtual file system is enabled to encrypt files without intervention from any file system in the plurality of file systems;
• computer usable program code for identifying whether a file on a given file system is an encrypted file using a map file associated with the given file system;
• and
• computer usable program code for encrypting, by the virtual file system, all data written to the file in accordance with encryption specifications in the map file in response to identifying the file as an encrypted file.

An apparatus comprising:

• a bus system;
• a communications system connected to the bus system;
• a memory connected to the bus system, wherein the memory includes computer usable program code;
• and
• a processing unit connected to the bus system, wherein the processing unit executes the computer usable program code to register a plurality of file systems on a data processing system with the virtual file system, wherein the virtual file system is enabled to encrypt files without intervention from any file system in the plurality of file systems;
• identify whether a file on a given file system is an encrypted file using a map file associated with the given file system;
• and encrypt, by the virtual file system, all data written to the file in accordance with encryption specifications in the map file in response to identifying the file as an encrypted file.
