Crypto System on a Label

Here is a postscript file which will print the following label on 1 x 4 inch labels. It looks something like this:


WARNING -- THIS LABEL IS CLASSIFIED AS A MUNITION RSA IN THREE LINES OF PERL HAVE YOU EXPORTED A CRYPTO SYSTEM TODAY? --> http://www.cypherspace.org/~adam/rsa/ --rsa--------------------------------8<------------------------------------- #!/usr/local/bin/perl -s-- -export-a-crypto-system-sig -RSA-in-3-lines-PERL ($k,$n)=@ARGV;$m=unpack(H.$w,$m."\0"x$w),$_=`echo "16do$w 2+4Oi0$d*-^1[d2% Sa2/d0<X+d*La1=z\U$n%0]SX$k"[$m*]\EszlXx++p|dc`,s/^.|\W//g,print pack('H*' ,$_)while read(STDIN,$m,($w=2*$d-1+length($n||die"$0 [-d] k n\n")&~1)/2) -------------------------------------8<------------------------------------- TRY: echo squeamish ossifrage | rsa -e 3 7537d365 | rsa -d 4e243e33 7537d365 FEDERAL LAW PROHIBITS TRANSFER OF THIS LABEL TO FOREIGNERS
A copy of the orginal label appeared in the New York Times.
