Isn't it amazing how long-standing threats to National Security only become _real_ threats when it is convenient for those in power? It was only a 'coincidence' that I happened to be standing in that bank that had been broken into, with a handful of cash. SynchronicityCriminal

Redhat crypto archive on replay

I forget where I saw the below message announcing stext for Linux, but there is a nice collection of crypto packages at http://www.replay.com/redhat . Unfortunately, they're in RedHat Package Manager format, so they may be a shade difficult to use for non-Redhat users, but Redhat does seem to be a fairly popular Linux flavor. >---------- Forwarded message ---------- >From: Hans Zoebelein <zocki(a)goldfish.cube.net> >To: redhat-announce-list(a)redhat.com >Subject: stext-1.0 stegano crypto package uploaded >Resent-Date: 4 Sep 1997 03:28:09 -0000 > >Hi, > >there is a nice crypto rpm, which uses steganograpic techniques >to hide a file in another text file which looks like normal text. > >The packages are stext-1.0-1.i386.rpm and stext-1.01.src.rpm >Binary and source should be dloadable from > >http://www.replay.com/redhat > >the next days.
