You might want to rewrote the multi-part section a bit more, though; with the loss of the flag bit, gzip is now entirely dependent on external split/combine utilities (not that anybody uses floppies anymore). >> Also, are you aware of _any_ gzip utilities that support encryption? > As far as I know, gzip has never supported it.

Info-ZIP saved a couple copies of PKWARE's and created several more versions to reflect our generic and OS-specific extensions (e.g., universal time, TOPS-20, OS/2 extended attributes, NT ACLs, etc.). You can find them here at the moment: http://www.info-zip.org/doc/ I think the only reason gzip refers to the 1991 version is because it was originally written in 1992 or thereabouts. Btw, the full crypto sources are here: ftp://ftp.info-zip.org/pub/infozip/src http://sourceforge.net/projects/infozip/files/ Not important now, of course. :-) Greg
