[0248] Using the WFL WRAP syntax, to pass the system DSA private key in the task attribute TASKSTRING, a Work Flow Language (WFL) job can then be created to automate the wrapping process.

[0249] In a Command and Edit (CANDE) session, do the following:

[0250] WFL WRAP AFILE AS WRAPPED / AFILE;TASKSTRING=

[0251] WFL WRAP ADIR / =INTO CONTAINERA; TASKSTRING=

[0252] It should be noted that the files can also be wrapped and signatured using a programmatic interface to the MCP-exported entry point MCP_FILEWRAPPER.

[0253] Wrap and Signature File:

[0254] FIG. 6 is an illustration of wrapping and signaturing a file. Here, it is seen that the wrapping sequence receives information from the DSAKEYSFILE. It also receives an input from the system DSA private key, in addition to receiving the file information, after which the wrapping sequence will produce the signatured file.

[0255] 5. To make sure that wrapped files are signatured correctly, it is desirable to verify these files before shipping them out t...

Abstract

A specialized data format native to a first platform is wrap-packaged into an industry-standard text file in a protocol suitable for Internet transmittal. A Signature Support Library provides parameters to combine with a User's private key to generate a signature particular to the data file being converted.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS:[0001] This application is related to a co-pending application U.S. Ser. No. 08 / 962,468 entitled "Method and System for Wrapping Single Files for Burning into Compact Disk", and to co-pending application U.S. Ser. No. ______ entitled "Digital Signaturing Method and System for Re-Creating Specialized Native Files from Single Wrapped Files Imported from an Open Network or Residing on a CD-ROM", each of which co-pending applications are incorporated herein by reference.FIELD OF THE INVENTION:[0002] This system relates to methods for enabling and signaturing data files which are organized in a first native format to be packaged (wrapped) and burned onto a Compact Disk and to enable the packaged files to be transported via standard protocols and utilized outside their native environment in networks utilizing different data formats.[0003] In the usage of modern computer systems and networks, the situation arises where systems having one proprietary...
