Abstract:
A method for wrap-packaging and signaturing a container of specialized first format data files and directory from a first specialized format into a second file in a second format compatible for burning onto an industry-standard Compact Disk, as well as for transmission on the Internet, wherein a primary sourced Operating System 10 of a platform 14 holds a first programmatic routine MCPFILEWRAPPER and a second programmatic routine MCPWRAPPER, plus a WRITE-WRAP routine, said Operating System 10 utilizing a Work Flow Language compiler 15 and Signature Support Library 13, and communicating with a secondary platform 30, said method for wrap-packaging and creating a digital signature to verify the validity of the container comprising the steps of:(a) initiating, by a user, of a WRAP operation together with a digital signature request;(b) utilizing the WRAP statement of Work Flow Language procedure for making a direct programmatic call to said routine designated as MCPFILEWRAPPER and passing a private key to indicate the request for a digital signature by utilizing said primary-sourced Operating System (MCP 10) to initiate said specialized routine designated MCPFILEWRAPPER;(c) obtaining digital signature parameter information from an active DSAKEYSFILE in said Signature Support Library 13, said parameter information being based on the particular Software Release level of the Operating System 10;(d) developing a link to said Signature Support Library in order to gain access to said Digital Signature Algorithm routine (DSASIGN);(e) calling said Digital Signature Algorithm routine of said Signature Support Library in order to digitally sign the ID with a ""source company name"";(f) calling said MCPWRAPPER routine in order to wrap-package a container file from a first specialized format into a second format compatible for the Internet and compatible for burning onto an industry-standard CD-ROM;(g) calling said WRITEWRAP routine in order to invoke the Digital Signature Algorithm routine to develop a digital signature for the wrapped container;(h) developing said wrapped container file together with its digital signature as a resultant file, so that said digital signature can later be used in subsequent operations to verify the integrity of the wrapped container.
