RSA in 3 lines of perl

Common .signature file for people who oppose the idiotic restrictions on cryptography imposed by the United States government.
The magic script is unreadable to any but the most advanced perl guru, but it does work.

!/bin/perl -sp0777i<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<j]dsj $/=unpack('H*',$_);$_=`echo 16dio\U$k"SK$/SM$n\EsN0p[lN*1 lK[d2%Sa2/d0$^Ixp"|dc`;s/\W//g;$_=pack('H*',/((..)*)$/)

This 3-line script is also famous for having been printed on the front of a t-shirt. I believe the gentleman behind it was Joel Furr. On the shirt, it showed the above three lines, together with a barcode version, and clear statement that the t-shirt was classed as a munitions and hence could not be taken outside the United States.

The back of the t-shirt featured parts of the United States Constitution (if I remember correctly, it was the first amendment), with a big VOID stamp on the back.

The shirt caused quite a furore; Joel Furr was actually arrested and faced court for printing and selling the shirts. I believe that this occurred in 1996.
