[comp.sys.mac] StuffIt Files at Simtel20.arpa

jpearce@pyr1.cs.ucl.ac.uk (04/18/88)

I have been trying to access some of the files at the
simtel20 archive.   The StuffIt (sit) files seem to be
in a binary format that seems unreadable to either the
unsit utility under UNIX or StuffIt itself on my Mac.
I have tried transferring the files using the image,
binary, and tenex modes under ftp but with no luck.   Unsit
complains that it cannot read the file header and that
the file is not in the StuffIt format.

What am I doing wrong ?

That might be nice, but those algorithms are EXPENSIVE.  If I remember
rightly, we would be talking about HOURS to encrypt/decrypt even moderately
sized files.  Large-scale DES requires hardware implementation.

For those of you who are waiting for the latest version of Stuffit, version
1.40a is available from the major online services (CIS, GEnie, Delphi, etc.)
and should be available on the net as soon as the moderator can get it up.

The new version supports encryption using a VERY FAST and VERY SECURE variation
on DES, as well as many bug fixes and other things that I will let Ray talk
about when he gets back from his vacation...

I believe (though have not tried it) that it will not retain Folder info if
you pack multiple levels of files (which is what you guys have been asking about
