Abstract
Encryption of virtual disc image is accomplished by increasing the size of a virtual disc to support the inclusion of a master boot record and a decryption program. Encrypting portions of a virtual disc image on the virtual disc, but leaving the boot record and decryption program unencrypted and accessible, where the decryption program will decrypt the encrypted portions if the appropriate cryptographic key is supplied. Subsequent decryption is accomplished by initiating a boot sequence through the master boot record, receiving the appropriate cryptographic key, appropriately ordering the decrypted disc image.
