Glenville T. Sawyer - South Australia Theatre, Concert Lighting, Special Effects, Props. & more ! Embedded Control systems for Theatrical & other Applications http://gsawyer.mtx.net/ And WOW !! - you should have seen the stuff I had to "weather" a few years ago, when I (mistakenly and openly) discussed (on the Amateur Packet & tcp/ip network) the D.E.S version that I had - fully operational (at that time) - it was well BEYOND the officially Exportable version level. I deleted all references to it, wiped the disks etc etc. Trouble was the code had been openly published in a U.S magazine that was available Globally ! So how does the NSA treat that ? O.k I no longer follow these things, but AFAIK 56 and 64 bit had been "cracked" a fair while ago, and PGP is not what it COULD be. Me ? - no - forget encryption, speak / type in "Assembly Language" - at least it narrows the field down a little Glenville.
