A method and system is provided whereby after specialized original native format data files have been signatured and &ldquo;wrapped&rdquo; along with a directory into an industry standard byte stream container file for transmission over the Internet (or for use of other computer platforms), then subsequently, the container of wrapped files with its signature can be accessed by a proprietary computer platform which will then use the signature to verify the integrity of the files and will unwrap or re-create these files back into the original specialized native format for use by the proprietary computer platform.

Digital signaturing method and system for re-creating specialized native files out of a container imported from an open network or residing on a CD-ROM

A container of data files and directory in a specialized first format are converted (wrapped) into an industry-standard text container file into a protocol suitable for Internet transmittal. A Signature Support Library and several procedural routines, together with parameters from the Support Library are utilized to combine with a user's private key to generate a signature particular to the container data file which has been converted. The container now with signature resides in a protocol suitable for transmission on the Internet or for burning onto a CD-ROM which is now usable for different platforms other than the original file protocol of a first platform which was only compatible with said specialized first format of the first platform.

Digital signaturing method and system for wrapping multiple files into a container for open network transport and for burning onto CD-ROM.

A system and method for transforming specialized data files of a first computer system into industry-standard byte-stream files usable for a second system or other systems. First and second programmatic interfaces of the first system can take the specialized format native data files and transform them into standard formatted byte-stream data files for placement in a storage media of a second computer system which can then be initiated to use a CD Writer package to cause the data files to burned onto a CD-ROM. This CD-ROM can then provide the byte-stream data file for use in many different types of platforms.

System for reformatting and burning of data files having a first format

Industry standard byte stream data files organized as a Container having a directory with multiple files on a Compact Disk are reconstituted to match the protocol of a first computer system's specialized native files in an integrated network where a second platform using standard byte stream Containers works in conjunction with a first platform having specialized native files. Specialized 'Unwrap' commands are effectuated by two programmable interfaces to take the byte stream data Containers and re-translate them to native-style files applicable to said first platform's operating system.
